If we can make our g++ compile C++11 code, then we can compile libc++ with g++. 
 This support requires significant modifications to the parser (it adds a 
second Turing-complete compile-time language, for one...) and so retrofitting 
C++11 support to g++ 4.2.1 is not going to happen.  It's taken upstream gcc a 
couple of years to get to the required level of support.  We don't have the 
manpower to replicate this.
