And my point is these runtime changes should just be added to the gnu  
runtime.

If you knew the history of this code you would blame the same person  
who is writing clang. I guess everyone forgets that the objc front was  
original written by Steve. I had hope to clean up the front-end but  
never got around to it because I always had better things to help out  
with inside GCC.

Let's see 68k, sh, hurd. The ppc64 support is weak at best. Debugging  
support is not really supported. Should I continue? I can go on and  
on. I guess I have anti-LLVM ever since Chris and Apple started to  
spread FUD.
