I have done a number of fixes and now I'm able to build libosmscout and 
run the import on your data (though Visual Studio seems to be much 
slower at some stages for yet unknown reasons. I'll do some profiling). 
Building OSMScout (Qt application) seems to be a little bit tricky since 
Visual Studio 2010 Express is neither directly supported by Qt (yet) and 
Express is not supported by Qt at all. I will test it first using MinGW. 
It would be nice if you could test the current version and give me some 
feedback!

I now have added support for the windows variant of memory maped files, 
which should drastically reduce file access time. The features is auto 
detected and does not require any defines to be set.
