That's actually a good idea. Now, I am a Linux person, but I have windows on a secondary machine. Compiling on Linux is trivial.

On Windows it is possible of course, WSL, msys, what not, but it is cumbersome. And I hate the default compiler on windows. So if coreutils on windows helps simplify all the base toolchain, I am all in favour of it. Windows really needs to make compiling stuff a LOT easier by default. I don't want to download some x GB of stuff I don't really need.
