Hi Gerd, It was removed in revision 4470. Prior to then 'anti-islands' surrounded by water were always converted to islands (there was no option as to whether this happened).

I only know the floodblocker option which is still evaluated in the source.

This was removed some time ago because it didn't work properly. I have put together the attached patch that works much better and have been using it for some time. With the sea data that I use, which contains quite a large number of incorrectly ordered polygons, it manages to correct every error it finds. It won't be able to fix really gross errors, but providing most of the data is correct it will produce good results. Please review and commit if happy.
