Even more clear: we have cross-compiled a Gnat Ada (upon gcc 4.3.7), 
which is up and running for our customer in France (line 14 of 
underground) ; you can get it here: www.vmsadaall.org .

It's a best effort initiative, very little means. But it worked, and if 
other customer use it we can go on and do more.

More:
- extending (our) specific Ada gcc to other gcc supported langages,
- doing the same cross-compilation for Alpha, to help and secure Alpha 
Ada users,
- thinking about llvm future for Ada.

Doing now (and because of that I'll have no time to rethorics, except 
serious things posted at www.vmsadaall.org):
- reuse dwarf information produced by gcc to integrate Ada debug into 
the VMS debugger.

For now VSI declined any project of collaboration. Too little, too 
risky. In french we say "pas de bras, pas de chocolat".
