   If you use the option "-std=c++0x" (instead of "-std=c++11"), it   
   should work with g++ version 4.6 (the most recent released version).   
      
   I don't have any personal experience with MinGW/MSYS, but I think it   
   shouldn't make any difference as long as the compiler version is   
   recent enough.   
      
   [I'm using a development version of g++,what will become 4.7 when   
   released (which does accept the -std=c++11 option).  Of course 4.7   
   supports more C++11/C++0x features, but the particular feature used   
   here (constexpr) was supported in 4.6 too.]
