Okay, I've checked my code, and I can rule that out. The only use of double variables is in a few printf instructions and our console. All according to the rules.

It's true that your code example produces this error when I add it to my main function, but the precompiler will continue and eventually start the game anyway.

During yesterday's test on the machine of the other 3DGS user however, it seems that the precompiler first throws the error, and then completely stops.

So... any other suggestions? I'd also like to emphasize again, that the project is starting up on other systems without this error.
