This is a Windows command line based cross development environment for Power PC built from the latest stable release of GCC (currently 13.1.0). I built 12.2.0 incorrectly so I've deleted it. Also included is Gnu make along with the necessary MinGW dlls to make it all work. I build tool chains for other targets, from time to time, to use for testing Flash Insight, a device programmer that is available on my website.
