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.
