--- Comment #2 from Martin Sebor <msebor at gcc dot gnu.org> --- I just happen to be looking into this. Is there a way to defer the option processing until after all this info is available? (When things like ptrdiff_type_node are already initialized, or at least when the target-specific data used to initialize them are set up.)
