Well. There isn't much left to do. In principle, if some transitional incompatibility was allowed, the game would be playable anyway. Just a few buildings and bridges, that were inaccessible in the nightlies anyway. Which brings a question:
should the missing objects be simply removed, or should I drop in placeholder graphics and hope that someone will create new versions?
sdog: These tools are certainly not needed, they just help me a lot with maintenance

If you want a hassle-free compilation though, get python, put makeobj in path, then execute pakmak.py I'm not sure if the export was complete though... I removed quite some unfree files.
