Could you send me the config you are having trouble > with? dont have it anymore - but you can look at the build error itself and figure out what config options it needs to trigger such problems - and whether the code could be simplified/streamlined to not run into such issues. If there's no #ifdef in a .c file there's rarely such problems. Ingo
