make ignore -std=c++11

I wrote a c++ program which contains "auto". And I've wrote the makefile: g++ -std=c++11 ... However, it still remind of "..does not name a type ..." I've searched on the net for solution but gain nothing. I think it might be a bug in make?? details can be found in appended pictures. ​ --
