I think the main problem here is that Nikolaus (and Riccardo) are using
platforms where there isn’t even a recent GCC available (IIRC Riccardo called
some time ago for keeping GCC 2.95 support — surely not for the pure fun of
supporting such old compilers). So even fixing GCC by adding ObjC 2.0 support
won’t satisfy some. What could be done about this? I have no idea …
