Add MSYS2 as a way of installing gfortran on Windows
At https://fortran-lang.org/learn/os_setup/install_gfortran , I think it's fine to keep equation.com as the 1st method to install gfortran on Windows, since it is simple and fast to install. I suggest adding MSYS2 as method fortran-lang/fortran-lang.org#4. I just tried it on Windows 10, and it works fine after following the instructions. Once installed, gfortran --version says GNU Fortran (Rev9, Built by MSYS2 project) 10.2.0 . It takes longer to install than the equation.com compiler binary but comes with more stuff, such as python. A list of MSYS2 packages is here.
I'll certainly let my students try to use MSY2 in my Fortran programming course next month, so we'll get some data points on how well this setup strategy works. I have already written a short introduction here which I could contribute.
I am using gfortran on MSYS2 for many years, to test gtk-fortran under Windows. It includes CMake, pkg-config, and all the classical tools you need in a UNIX-like environment. It is slower than on a native Linux environment because many things must be "translated" to make programs work under Windows, but it is very usable.
