What is MinGW and how is it used?

MinGW is a toolchain designed to bring Unix-based compilers and libraries, particularly gcc, to Windows. It allows software originally made for Unix systems to be built and run on Windows without having to completely port it to MSVC manually. This can save a lot of effort when transitioning projects to a Windows environment.

Another advantage of MinGW is that it comes with Git for Windows, part of Git-Bash. This is super handy if you're in an environment where you can't get admin access and WSL isn’t an option. It keeps things simple for compiling and running C programs.

In today's world with WSL (Windows Subsystem for Linux), MinGW might feel a bit outdated, but it's still very relevant for specific use cases. You can easily distribute a MinGW application as a standard Windows app. Plus, with WSL, your users need to have it set up, whereas MinGW apps can run without that requirement.
