--- Comment #12 from Francois-Xavier Coudert <fxcoudert at gcc dot gnu.org> ---
Regarding the last few comments: all this comes, AFAICT, from the front-end not
recognizing "instancetype". I don't think we can get out of this by fixing
headers or anything else: it's an extension to Objective C, and if Apple is
going to use it widely, we need to support it in our front-end.

I know it's not very helpful, because I cannot code the changes myself. I've
tried to look at the front-end code to see where "id" is defined, but it's not
very clear.

In any case, what I wanted to say is: I don't think we need more analysis of
this. We need someone who can do the work :)
