I had some success using RTools40 and the corresponding R testing version. I had to do a lot of MSYS shenanigans and couldn't get static compilation to work, but the binary package seems to work just fine in R 3.6.2.

It makes me very happy to see that R will get an updated toolchain and a proper MSYS environment with a package manager! Is there a due date for R 4.0.0?

You will have to wait.

The current Rtools is at g++ 4.9.3 which (barely) supports C++11.  We all
keep our fingers crossed as the replacement Rtools would bring g++ 8.*.  This
may happen with R 4.0.0 in April but I have no more details either.
