BTW, the compilation is successful.

I've not tested so far.

Yes, I wasn't quite correct. I should have said "bootstraping like
lang/gnat do".

Gnat with gcc4x has GPL like all gcc code. I'm not an expert here but
it seems that bootstrapping with gnat/gpl may have result in pure GPL
license. That's why I prefer to have a possibility to bootstrap with 
gnat-3.15p-boot.
