[mkgmap-dev] Missing island names

Marko,

first of all: you should not run mkgmap with the patch I created for 
you. I don't know for sure but this patch might have an impact on the 
tagging.

If you have the same problems without the patch it might also be caused 
by the generate-sea code. Copying of names from original ways to the 
artificial multipolygon ways seems to be a bit inconsistent. Or in other 
words: I didn't understand some parts of the tag handling there :-)
Maybe it's worthy having a look on it.
