How to use MSYS2/Mingw-w64 GCC compiler instead of Microsoft Visual Studio?

[Foadsf]

To solve my problem as described here, I did some research. From here I realized that the Clang/LLVM

doesn’t provide a stdio.h, it should come from your C standard library implementation, whatever that is

so reading the release page of this repository again, I see that an MSVC installation has been instructed. Now I am wondering if there is a way to use MSYS2/Mingw-w64 GCC compiler installed in C:\tools\msys64\mingw64\bin\gcc.exe instead?

P.S. I asked a follow up question here.
