Possible issue with make-win32-release script

[Ryochan7]

While attempting to initially build the Windows version from the c branch code, the script kept encountering problems with missing DLL files. I tried using some of the GTK+ Runtime Environment files from the last Windows pre-release of SC Controller but that did not work out. After some experimenting, I found the bundled GTK+ Runtime Environment files that are available in my MSYS2 installation. I can build and load SC Controller fine now.

I installed MSYS2 using the 20200522 installer. I should be running the most recent base as I just updated the system packages using pacman before testing today. Here is a small diff showing the changes I had to make to ensure that the build script would work. I am not sure if any changes would potentially interfere with your setup so I thought it would be better to submit an issue rather than a pull request.

I'm usually updating those only when building new release. But this looks harmless. I'll try to update my windows machine and I don't think it should interfere with anything.
