507 bfd_som_set_subsection_attributes): Change parameters from char

592 * elfcode.h (swap_out_syms): Use elf_section_from_bfd_section to
593 get the index of a common section, rather than always using
594 SHN_COMMON (MIPS has multiple common sections).
596 * elf32-hppa.c (hppa_elf_gen_reloc_type): Typo (== for =).

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

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

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