If GNUstep stayed with GCC, those missing functionalities can not be 
implemented at all; while if GNUstep dropped GCC, we can start working on those 
features and libraries.. From a practical standpoint, I would consider GCC’s 
Objective-C support broken beyond repair by this point really, since those new 
libraries and functionalities depends on entire new language features like 
Objective-C ARC, Blocks and extended Objective-C language. And there is the 
whole new can of worms of Swift integration, which requires the use of 
LLVM/clang since Swift itself is built on top of it, and there is no Swift in 
GCC at all.

As of LLVM/clang doing a better job at supporting the language, it is because 
Apple is on of the main contributors and actively feeds their language changes 
back to the mainline.
