MinGW-w64 Installation
I stopped using http://mingw.org/ ages ago as it was getting behind on newer Windows API additions and newer gcc versions.
Instead I really recommend MinGW-w64, which supports both Windows 32-bit and 64-bit.
If you want to keep your old MinGW on your system and would like to give MinGW-w64 a try without interfering with your installed version, you can download a standalone build from http://winlibs.com/ that you just need to download and extract.
If you use MSYS shell you should also switch to the newer MSYS2, which is a lot faster.
I guess they've stopped paying for this domain.
The good news is that MinGW is still available on MinGW - Minimalist GNU for Windows download | SourceForge.net. Note that the maintainer announced on the homepage:
This project is in the process of moving to osdn.net/projects/mingw, you can continue to follow us there.
So you may need to go to MinGW - Minimalist GNU for Windows Project Top Page - OSDN.
Factsheet
GCC 10 is officially released. The personal build for Windows (MinGW-w64) that can be downloaded from https://winlibs.com requires no installation, just extract to a folder.
Building GCC on Windows from source code is very difficult and cannot be recommended to beginners. Moreover, GCC 10 has not yet been officially released and you may need to wait a few more weeks to get it.
If you want an up-to-date GCC in Windows (currently version 9.3), I recommend downloading and installing the MSYS2 package. Once you install it, launch it using the "MinGW64" icon and install the correct compiler in the terminal. For details, see this question: How to install MinGW-w64 and MSYS2?
Once you have done this, you can forget about MSYS2 and simply use the directory with the binaries in your PATH.
The maintainers of MSYS2 are very keen in supporting bleeding edge software, so once GCC 10 is released, you will be able to update to it (using the command pacman -Syu)
very soon.
