I think these may have been caused by the recent GNUStep changes.

It works fine on GNUstep too, so I’ve pushed the change.

FWIW, that instancetype type appears to be a built‐in and we should
probably be doing some sort of check whether the compiler supports it
natively or not. I don’t know how to go about doing that.

This warning doesn’t make much sense to me. I’ve looked up the
documentation and the new method being used has allegedly been
available since macOS 10.5.


I guess if it’s working we can just ignore it.
