title: How to build or get a original latest version of GCC for Windows?
body: <p>I want a latest version of GCC for Windows.
  Now the latest version is 9.2 but for Windows via MinGW it is just 8.1...
  I have tried to build from source for Windows 10 include WSL, but have not found how to do it exactly, I do not want use via CygWin or other emulater, just real on Windows as clang and MSVC.
  Note: I have Windows 10 latest version with WSL.</p>
