Rtools and R 4.0.0?

That's great to see, although I suspect it's still a speculative
change and could be backed out if any non-trivial issues were
encountered.

Regardless, I would like to thank R core, CRAN, and Jeroen for all of
the time that has gone into creating and validating this new
toolchain. This is arduous work at an especially arduous time, so I'd
like to voice my appreciation for all the time and energy they have
spent on making this possible.

Best,
Kevin

There appears to have been some progress on this matter:

-Note that @command{g++} 4.9.x (as used for @R{} on Windows up to 3.6.x)
+Note that @command{g++} 4.9.x (as used on Windows prior to @R{} 4.0.0)

See SVN commit r78169 titled 'anticipate change in Windows toolchain', or the
