Sorry I haven't got time to go through this in detail at th emoment - but 
I just wanted to say, this is good stuff!

Hmmm, the intent was to remove the dependency of gnattools on libada 
rather than the reverse : I need to build gnattools even when libada is 
not being built. Did I get that wrong way round?

It's true that having added that patch, that source tree is broken as far 
as building native gcc and that's not ideal. I'll have to think about 
your solution... alas, not today.
