added compiler (and it's version) detection

Browse Source 
This should fix problems with different flags for c++11 across different gcc
versions. Should compile on Clang and gcc >= 4.6. Lower versions of gcc are
untested. I don't even know wheteher they support c++11 (gcc 4.2.1 on OpenBSD
5.7 does not).
