It complains about some C++ syntax. Adding C++11 support on line 20 will make it compile and work properly. Can you please add this change?

Issue google/googletest#1323 gives a code update fix for 1.7.0; replacing NULL with nullptr.
Is this package 'drop-in' compatible with gtest 1.7.0? I suspect it might not be due to the version difference.
