If we reference the field as "super_class", we won't be compatible with
gcc <= 3.4. That isn't an option for GNUstep.

Yes. Not pretty, but FWIW, the same pattern can be seen in several other
headers here.

It isn't optimal, but that's the price of compatibility. We do need some
way of writing code that will work with "all" versions of gcc. This
can't be the first time there's a name conflict like this, so there may
be some established way of dealing with it. #ifdef __cplusplus is the
only one I recall seeing.
