Yes, it is written in C++. I tried in that format what you have 
explained. This is why I ask for help on the list (Because I can't 
figure out witch is the correct format of the struct in this situation - 
the black spot is around the "AST_DECLARE_STRING_FIELDS"). Maybe 
somebody can give me a simple example with the correct format in C++?

Thanks for help, and sorry for noob questions.
