I have started to add BOOST_NO_CXX11_U16STRING and 
BOOST_NO_CXX11_U32STRING (see attached patch) and at the end I'm getting 
an error for gcc-4.7.0 -std=c++0x which has nothing to be with my 
modifications.

boost_no_cxx11_hdr_mutex.ipp: In function ‘int 
boost_no_cxx11_hdr_mutex::test()’:
boost_no_cxx11_hdr_mutex.ipp:21:14: error: ‘std::timed_mutex’ has not 
been declared
boost_no_cxx11_hdr_mutex.ipp:22:14: error: ‘std::recursive_timed_mutex’ 
has not been declared

In addition I'm unable to build the docs

are these know issues?

I have updated only the file boost/config/stdlib/libstdcpp3.hpp. I could 
update others once you commit the patch.

Best,
