[Rd] Rtools and R 4.0.0?

[Kevin Ushey]

Hello,

Has a decision been made yet as to whether R 4.0.0 on Windows is going
to be built using the new gcc8 toolchain (described at
https://cran.r-project.org/bin/windows/testing/rtools40.html)?

>From the sidelines, I can see that the toolchain is being used to
build and test packages on CRAN; if there are any remaining issues
that I can help to try and run down (either in R or any CRAN packages)
I'd be happy to try and help.

FWIW, I'm excited at the prospect at seeing a new toolchain for
Windows, since it would imply support for C++17 and so it would become
easier for CRAN packages to depend on the newer C++ standard.

Thanks,
Kevin
