Rcpp with c++11 flag in Windows: unrecognized command line option -std=c++11

I wrote a Rcpp code which works fine in linux, But When I want to run it on University labs which have Windows machines. I get this error:

error: unrecognized command line option '-std=c++11'

As in this answer I used -std=c++0x, But it not working on my code.

Question is: How Can I update g++ in windows. Any other suggestion?
