924 (MY_bfd_make_debug_symbol): Rename from MY_make_debug_symbol.
925 (MY(vec)): Use JUMP_TABLE rather than listing functions.
926 * hp300hpux.c (MY_get_symtab, MY_get_symtab_upper_bound,
927 MY_canonicalize_reloc, MY_write_object_contents): Don't define in
928 terms of MY, because that causes a recusive invocation of CAT when
929 expanded within JUMP_TABLE, and ANSI compilers don't expand
931 * mipsbsd.c (MY_bfd_reloc_type_lookup): Rename from
932 MY_reloc_howto_type_lookup, and don't define in terms of MY.
933 (MY_canonicalize_reloc): Don't define in terms of MY.
934 (aout_mips_little_vec, aout_mips_big_vec): Use JUMP_TABLE rather
935 than listing functions.
