Writing an O/S of any kind at the time they started would have required that everyone involved purchase a compiler, or make-do with some simple shareware one. So I don't find any fault with their approach, because they simply had no other choice (also thanks to this effort in part, we have GNAT). In the AdaOS case however, I don't feel that it was essential to create a new compiler. I think Nick even expressed his reason as being one of "wanting to do that", which is fine (people should enjoy what they do in their spare time). I'd even welcome additional free Ada compilers to choose from but, I feel that this is a rather ambitious undertaking, when you're planning on delivering an OS as well. -- Warren W.
