Though I know nothing about GNAT, I know a bit of setting up
cross-compilers. If the host and target architectures are both known
to the tools (compiler, linker, assembler, other binutils), and if you
have includes and libs available, it's not very complex. I've put in
NetBSD support in the FSF tools and played around little with
cross-compilations. The only thing I know of which isn't supported
today, is the generation of dynamic NetBSD binaries, which would be
nice to have, but not essential. I'd like to add that support at some
time but have too little time now.
So, go for it, a cross-compilation environment shouldn't be too hard,
IMO. Unless of course GNAT itself is hard to setup as a
cross-compiler, which I doubt, knowing Kenner is involved in GNAT.
