        * except.c: Include intl.h.
        (expand_eh_return): Set current_function_cannot_inline.
        (save_eh_status, restore_eh_status): Twiddle eh_return_stub_label.
        * function.h (struct function): Add eh_return_stub_label.
        * flow.c (delete_unreachable_blocks): Don't merge across EH edges.
        * Makefile.in (except.o): Depend on intl.h.
