[Rcpp-devel] Windows set C++11 flag for new compiler

[Charles Determan]

Martyn,

This ultimately solved my problem.  However, I also needed to set CXX1X as
R continued to try and use the 4.6.3 version.  Once both CXX1X and CXX1XSTD
were set in the HOME/.R/Makevars.win file, the compilation ran successfully.

Thanks,
Charles
