Hi Thorsten,

I don't know how. But you don't need to create the bounds from a world file.
It is possible to create the bounds for several overlapping subareas and 
to merge the bounds files afterwards. The areas must be selected in such 
a way that each country is completely contained at least in one subarea. 
Usually I am compiling 5 subareas: europe, africa, america, asia and 

After you have the bounds files of your subareas you can merge them 
using the command:
java -cp mkgmap.jar 
uk.me.parabola.mkgmap.reader.osm.boundary.BoundaryMerger <bounds1> 
<bounds2> <merge>
where the parameters in <> are directories. So in the upper command the 
dir bounds1 and bounds2 are merged together in directory merge.
