[PATCH] Work on a dive localisation tool using GPS coordinates

So this requires http://nzjrs.github.com/osm-gps-map/ - which seems to
not be available as precompiled library for cross compilation on
Windows (at least not on Fedora), nor does it appear to be in the Mac
repositories that I usually use.
I can apply this now and potentially break the builds on Mac and
Windows. The fact that Henrik (our Mac maintainer) has sent patches
makes me think that he's a step ahead of me. Lubomir, have you looked
into this package on Windows?
