There seems to be a problem using Rcpp::plugins("cpp11") on Windows
8.1.  It gives the error:
cc1plus.exe: error: unrecognized command line option '-std=c++11'

I am using Rtools 3.1.0.1942 (which is the latest version) and for
that it needs -std=c++0x or -std=gnu++0x

If I remove the plugins line and instead issue this line first then it
all works (except as per prior email I built Rcpp without vignettes to
get around that problem):
Sys.setenv("PKG_CXXFLAGS"="-std=c++0x") # for gcc 4.6.3
