Re: OS in Ada, what about the compiler?

It has been done.

But for what your trying to do you should check out:

RTEMS -- Real-Time Executive for Multiprocessor Systems.

         http://www.rterms.com

         CPU Systems: AMD 29K; Hitachi SH; HP PA-RISC; 
                      ix86, i960; m683x0, m680x0, mPPC, 
                      mColdfire; MIPS R46x0, SPARC.
         Download: Source only

MaRTE -- Minimal Real Time Operating System for Embedded 
         Applications is a real time kernel

         http://marte.unican.es/

         CPU Systems: x86
         Download: Binary, Source, Demo programs.

Both are rated as a Real-Time GPL open source OS with Posix 
interfaces. They use GNAT for their Ada compiler.  

There are other projects out there if you spend a few minutes 
using your search engine you can find them. Like the Toy 
Lovelace project but on their web site there are no files listed, 
even though the project was started in Jan 2006.
