First of all, thanks so much for the detailed response. I managed to get a hello world example to compile with 4.2.2, thanks to your help: http://i.imgur.com/he4IihL.png

Interestingly, I did not need to do everything you described in your mail. I'm not sure why. I did do a few other changes to the Makefile a few days before, so possibly I've already fixed whatever problems there were—I can't remember everything I specifically did. I'll know once I copy over these changes to my repo so I can see in the diff exactly how it's different from the vanilla 4.2.2 release. I also intend to write an article/tutorial about this.

I did, however, need the -fgnu89-inline. That was an essential part of the puzzle. After that, it complained about "saved_ds" being an undefined reference. I went into the code and simply removed its "static" declaration.

Yes, I was not expecting it to work at this point. I didn't get any of these other dependencies. Maybe I will in the future as I start actually working with it, though. I'm sure other errors will crop up.

You've been a great help, thanks again.
