This as well as the modification I checked on Windows-MinGW compiles 
well in MacOs for 
darwin-4.7.0x,darwin-4.6.2x,darwin-4.7.1x,clang-3.1xl,clang-3.2xl,darwin-latest_11,darwin-4.7.2x. 
on C++11 mode.

I will check your example tomorrow on MinGW. Could someone else check 
this simple example on MinGW with compiler supporting noexcept in C++11 
mode?
