Omg I’m totally starstruck now!

Purely out of curiosity, was that all a volunteer open source effort or was the entire DJGPP group acting as a consulting organization?

The DJGPP project and its contributors were 100% volunteer. I'm sure some of the contributors took advantage of their involvement to obtain consulting gigs on the side (I did ;) but DJGPP itself didn't involve any. The Quake work was a swap; we helped them with optimizing, and they helped us with near pointers. Win-win!
