Comment 11 for bug 544036

I Just recently had time update the branch up to current trunk. But I think this should be ok for merging, and I'd like to get it in finally. So I'll see there are any comments on merge request.

While getting the tests to run, I fixed some file system special cases for windows, changed file system code to allow using relative paths on command line, and hard coded windows version to use executable path as default search path - just like in Mac. Earlier this was done using dots in paths during building.
