It is a long time ago (~2012) that I added and fixed the MinGW/Msys build [1] on Windows. We at SAP used it productively for some years because at that time Cygwin was terrible slow, buggy, had no 64-bit version, wasn’t really maintained very well, etc...
But things have changed to the opposite since then and we‘ve switched to Cygwin at least 3 years ago (can‘t find the exact date now). As far as I know, there haven‘t been any serious users of the MinGW/Msys build since then. At that time MinGW/Msys had some serious problems which made it impossible to do parallel builds. Not sure if that has been fixed by now? I personally always liked MinGW/Msys compared to Cygwin because of the (at least in my eyes) more intuitive way of handling Unix/Windows paths it’s simplicity and speed. I’m not sure however if it is currently actively supported, and if the old problems have been fixed. So to finally answer your question :) I don’t think anybody is currently using the MinGW/Msys build and I doubt that it will work without bigger adaptions and fixes.
