Hi WanMil,
The patch closes all ways having both endpoints on the same side outside the bounding box. In this case it is not necessary to check if closing the way intersects the way itself.
This fixes most (but not all) of the outstanding tile splitter problems.
I still see some warnings presumably due to tile splitter, but other than that, this and mp_lesscuts_v2.patch look fine to me. Compared to the unpatched mkgmap r1593, these two patches shaved more than 11k off the warning log (181452 bytes for today, 192079 for yesterday, even though today's run contained many non-multipolygon warnings).

Torsten Leistikow pointed me to another problem with the tile bounds. In case a polygon was splitted by the bounding box into different distinct polygons only the first of it was taken. Version 2 of this patch handles this case. Summary for version 2: - Closing ways with both endpoints outside the bounding box and with both orientation towards the bounding box. - Bugfix: if a polygon was splitted by the bounding box into different distinct polygons only the first of it was taken. Now all distinct polygons are processed. (thanks to Torsten Leistikow) I give a very big "GO for commit" to this patch :-) WanMil
