Currently, no. In the next week I will write up complete instructions 
and send them off to the AVRLibC project, as they have an open 
request for build instructions for Windows. I'll send you a copy of 
it then.

If you're already familiar with the process however, here's the 
(extremely) short answer:
1. Need good working bison and flex.
2. Need patch for GCC.
3. Current MinGW version.
4. Need MSYS 1.0.8-rc-2 (release candidate 2). CAUTION! MSYS 1.0.8 
released will NOT build GCC correctly. I just spent a week figuring 
this out.
5. Build with the *nix build instructions listed in the AVRLibC 

In WinAVR 20030115, the utilities contain the bison and flex I use. 
The source download contains the GCC patch.

Now, I don't know anything about Ada, but what about the library? 
Will it have to have a separate library for Ada?

Let me know if you can get the Ada frontend working for the AVR. I'd 
also like to know how to build it too and how to use the Ada 
compiler. If it can make working code and it's not a huge addition, I 
would be interested in adding it to WinAVR.
