Some 25 years ago I was tasked with writing a certain driver for Windows. Being totally migrated to Linux by then I refused to use Windows for writing as well as building it, so I worked hard to build it with MSYS. Long story short, I made it, and the driver worked great. I think I had to write a patcher for the resulting PE (.sys) to get it to actually load. Fun times.
