New description:

 clang3.1 seems to be compiled with c++03 support and not c++11 support
 it does not compile boost based code

 e.g try to compile the following one line code :

 {{{
 #include <boost/signals2.hpp>
 }}}

 and it fails.

 it seems that clang 3.1 is actually using an old (from apple) libstdc++
 (4.2) library which is c++03 and not the latest one eg from gcc 4.6 or gcc
 4.7.
