[Rcpp-devel] g++ flags

[Romain Francois]

The plugin as implemented now is not portable. The easiest way to make it portable would be to define the USE_CXX1X environment variable, which R knows how to interpret. 

This way R would do what makes sense, i.e. use -std=c++0x on windows (for which rtools is limited to gcc 4.6.3 now) and -std=c++11 when it makes sense.
