 // For XCode >= 4.6:  the compiler is clang with libc++.
 // For earlier XCode version: the compiler is gcc-4.2.1 with libstdc++.
 // libc++ provides <unordered_map> and friends even in non C++11 mode,
 // and it does not provide the tr1 library. Therefore the following macro
 // checks against this special case.
 // Note that we should not test the __APPLE_CC__ version number or the
 // __clang__ macro, since the new compiler can still use -stdlib=libstdc++, in
 // which case <unordered_map> is not compilable without -std=c++11
