Is this not the strongest argument to deprecate GCC, and just build on Clang/LLVM? If feature parity with Apple's API is the goal, isn't this kind of a requirement at this point? There's other rather large projects moving purely to a llvm toolchain (android ndk), so it wouldn't be totally unheard of. They've deprecated gcc and are removing it entirely in a future release.
