On what arches does gnat currently work ? I'd like to try to build it on openbsd architectures, I have i386 binaries... I've tried cross-building i386->sparc64, with little success. I'd like to know which processors are happy with gnat in 3.1 (or the 3.1 branch), and whether cross-compiles have a chance to work, before I embark on a wild goose chase...
