[mkgmap-dev] Sea (or lakes) bug

From WanMil wmgcnfg at web.de on Sat Mar 26 10:07:51 GMT 2011

I have posted a first patch. Using that patch your example works with 
generate-sea=multipolygon. At the moment I have no time to check that 
patch in deep and if it completely covers all situations.
Please check it yourself. I will need at least one week to do the rest.
