The diagnose_mismatched_attributes has been simply placed way too early, before we check if the two decls actually shouldn't be merged because they have different arguments (and not extern "C"). I'd say we should just say this is fixed for 9 and decide how to fix on release branches. Let me prepare a patch with some testcases for trunk.
