about gcc native on Microsoft Windows

[Arie anony]

I have tried many options to get latest gcc for Windows 10 no via MinGW,
CpgWin and other and not found how do it exactly.
I want to build native gcc for Windows, can also via Linux or WSL and then
move to run on Windows.
Is GCC build from source support also build for Windows or only POSIX
compliment operating systems as UNIX, Unix-like and linux?
