We do not use these features in our code.  Those features are used in the Apple system libraries.  The result is that NS Emacs cannot be built using GCC at all, and that is not new.

The patch being discussed adds xwidget support to an Emacs configuration that cannot be built with GCC, so I think it's okay to rely on clang for building it, as we did in the past.  Especially since extending GCC's ObjC implementation is nig a priority for the GNU project.
