--- Comment #2 from Richard Henderson <rth at gcc dot gnu.org> --- While that does allow me to proceed further, I think you're dismissing an actual problem somewhere. If gnat 4.8.2 can compile gnat 4.9.0 for native, then I do not understand why it can't compile 4.9.0 for cross. It seems like you've got a search path problem somewhere.
