Thu Feb 25 15:40:07 GMT 2010

I too ran into problems using the patch (on Austria from geofabrik):

Exiting - if you want to carry on regardless, use the --keep-going option

Maybe both Marko and me am using some other patches that break something 
here?
--- therefore attached my patches to mkgmap I'm currently using (except 
a bit copyright info changes for maps created, mainly a patch to change 
dp filter independantly for polygons).
