753 * aoutx.h (aout_link_check_ar_symbols): Correct test for whether

788 (coff_write_symbols): Initialize debug_string_size to 0. If
789 bfd_coff_symname_in_debug returns true, don't put symbol name in

816 keep the value in the ECOFF symbol. This helps gas.
818 * linker.c (_bfd_generic_link_output_symbols,
819 _bfd_generic_link_write_global_symbol): Don't require that all
820 references to a common symbol be themselves common symbols.

897 bfd_som_set_subsection_attributes): Change parameters from char
898 to int. Following a prototype with an old-style function definition
899 in the presence of widened parameters is a GCC-ism not supported

1035 The sparc (and possibly other?) NLM format requires a different
1036 way to write exports, so add a write_export field to the backend
1037 data (and set it to NULL for everything but the sparc).

2320 MY_canonicalize_reloc, MY_write_object_contents): Don't define in

2322 expanded within JUMP_TABLE, and ANSI compilers don't expand
2324 * mipsbsd.c (MY_bfd_reloc_type_lookup): Rename from
2325 MY_reloc_howto_type_lookup, and don't define in terms of MY.
2326 (MY_canonicalize_reloc): Don't define in terms of MY.
