Somewhat urgent, because there is a pretty bad bug where using_gcc49() returns T even when using gcc 8.3.0.
R 4.0 has much improved defaults for CC and so on. It will automatically find the correct rtools40 path based on RTOOLS40_HOME. The best thing you can do is not change anything.
The one thing that pkgbuild may want to do is put ${RTOOLS40_HOME}\usr\bin on the PATH if the user hasn't done so yet.
