std::vector is part of C++, not of C. Having a init function like this 
requires the robots to be written in C++: C is not an option any more after 
this change. I don't know for sure if pure C-robots are possible at the 
moment.

I don't know much about the Windows build.

I also made something like this some time ago, but I did it on a slightly 
different way. The problem I wanted to solve is that it is hard to drive 
against 10 formula one cars, for example. So I added a way to select a robot 
and a car (the list of cars is limited by the robot) and add such a robot. So 
you can add 15 identical robots of the same car type.
