388 bfd_coff_symname_in_debug returns true, don't put symbol name in

607 undefined, look it up in the linker hash table.
609 * aoutx.h (translate_symbol_table): The string index 0 has a
610 special meaning for normal symbols, but not for dynamic symbols.

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

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