* write.c (is_dnrange): Do not define if md_relax_frag is defined.
(relax_segment): If md_relax_frag is defined, use it to handle a frag of type rs_machine_dependent rather than looking through md_relax_table. * write.c (relax_and_size_seg): Don't set SEC_HAS_CONTENTS for a bss section. Set SEC_RELOC if there are any relocations, even for a zero size section. * write.c (write_relocs): In RELOC_EXPANSION_POSSIBLE case, based data offset on reloc[0]->address rather than reloc[j]->address, so that multiple relocs can affect different memory locations. * write.c (chain_frchains_together, relax_and_size_seg, adjust_reloc_syms, write_relocs): Make third argument PTR, not char *, to match definition of bfd_map_over_sections.
