 692         BFD_RELOC_MIPS_LITERAL, BFD_RELOC_MIPS_GOT16,

 705         (MY_bfd_reloc_type_lookup): Rename from

 710         MY_canonicalize_reloc, MY_write_object_contents): Don't define in
 711         terms of MY, because that causes a recusive invocation of CAT when

 714         * mipsbsd.c (MY_bfd_reloc_type_lookup): Rename from
