How to switch on C++11 on Eclipse?

This is, somehow, quite annoying me. I was compiling C++11 on Eclipse Kepler, but there was an error (as shown below) complaining to me that I must enable C++11 in order to proceed. But where is the C++11 switch?

The switch was locate at project's properties > C/C++ Build > Settings > Tool Settings tab > Cygwin C++ Compiler > Miscellenous, put -std=c++11 in the Other Flags to switch on C++11 (append on it if it is not empty). Then the compilation will proceed as usual.
