504 bfd_som_set_subsection_attributes): Change parameters from char

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

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

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