Good catch. I think I also noticed at least one other package using C++14 with the current toolchain (xtensor) and it used eg by one other package (rray) which has an even simpler src/Makevars.win just setting CXX_STD as advised (plus tweaks to PKG_CXXFLAGS, see https://github.com/r-lib/rray/blob/master/src/Makevars.win So notwithstanding my earlier message Guido's package should work with the current Rtools.
