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

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

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