http://josm.openstreetmap.de/ticket/7061 has a working patch for the 
validator, so I guess this one does not need to be addressed in mkgmap 
unless it is very easy to do.

My standard workflow for coastline errors (and yes, mkgmap did produce 
them, but they were unhelpful in this case) is to extract the 
natural=coastline ways from the map extract (splitter input) with 
Osmosis, and then run JOSM Validator on it.
