C++ is not C. The C++ standard says these are keywords and not defines  
which is unlike the C standard.

------- Comment #4 from pinskia at gcc dot gnu dot org  2010-03-13 04:37 -------
Use -fno-operator-names if you want these keywords not to be keywords in C++. 
Closing as invalid because these are keywords in C++.
