[boost] [system] Do we need this library with latest (almost C++0x) compilers?

Can somebody please explain what is missing in current compiler implementations?

What is preventing other libraries to have a macro like:

#ifdef _CPP11_THREAD_
    #include <thread>
    #include <mutex>
    #include <condition_variable>
#else
    #include <boost/thread.hpp>
    #include <boost/thread/mutex.hpp>
    #include <boost/thread/condition_variable.hpp>
#endif

 also when it comes to error codes and conditions?

Thanks,
Tony
