I tried that and that fixed most errors.

I tried to find the culprit, and in the end I was so frustrated I started to copy stuff to a separate project to troubleshoot. I was able to build some minimum failing example, the bare minimum that fails.

In that example, I still can't understand why it fails, but see for yourself:

In the puzzles project, it is noticable that nullgame.6, blackbox.6 and cube.6 all have different type signatures for basically the same piece of code (using the same type from the same include file).

Not sure if that's a compiler bug, maybe.
