Comment (by anonymous):

 Another suggestion: the availabilty of C++11 features may also (should) be
 tested by checking _ _cplusplus
 http://gcc.gnu.org/ml/gcc-help/2011-05/msg00355.html


 This macro is defined in the C++ Standard and independent of the specific
 compiler, be it GCC or Clang.

 GCC 4.7 is cheating, however, they set _ _cplusplus to 201103L, but
 haven't fully implemented the new features. This happened in GCC 4.8.1
 only: http://gcc.gnu.org/gcc-4.8/cxx0x_status.html
