613 * aoutx.h (translate_symbol_table): The string index 0 has a
614 special meaning for normal symbols, but not for dynamic symbols.

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

887 in the backend accessor macros; that should no longer be possible.

1928 MY_reloc_howto_type_lookup, and don't define in terms of MY.
