Subject: [Rd] R 3.4 has broken C++11 support

Hi, 

This commit (I?m using the mirror to have a working link) broke C++11 compilation. 

Before (and still now, according to the comments in the configure script), it?s sufficient to just have ?SystemRequirements: C++11? in the DESCRIPTION file. 


But now ?R CMD install? fails with ?C++11 standard requested but CXX11 is not defined?, which is, according to the documentation , a lie. 

I can?t even circumvent this, as setting ?CXX11=$(CXX)? in the src/Makevars file fails with ?CXX definition recursive?, and hardcoding ?CXX11=g++? is a bad idea. 

Did I do sth. wrong or is the C++11 support in R just broken atm.? 


Best, Philipp 

PS: After addressing all points in the submission of my popular package ?IRkernel?, I didn?t get any feedback, and the file just vanished from the incoming directory in CRAN. I asked about it multiple times but got no answer. What can I do now?
