From Eric Youngdale <eric@andante.jic.com>: 

* elflink.h (elf_link_add_archive_symbols): If a default symbol is
	not found, try looking it up again without the version name.
	(elf_link_add_object_symbols): Always link against the dynamic
	symbol table of a dynamic object.  When linking against a dynamic
	object, include version strings in symbol names, and set up
	version information.  Add indirect symbols for default versions.
	(elf_link_create_dynamic_sections): Add special version sections.
	(struct elf_assign_sym_version_info): Define.
	(struct elf_find_verdep_info): Define.
	(NAME(bfd_elf,size_dynamic_sections)): Add verdefs parameter.  Set
	up version sections.
	(elf_adjust_dynamic_symbol): Ignore indirect symbols.
	(elf_link_find_version_dependencies): New static function.
	(elf_link_assign_sym_version): New static function.
	(elf_link_renumber_dynsyms): New static function.
	(struct elf_final_link_info): Add symver_sec field.
	(elf_bfd_final_link): Initialize finfo.symver_sec.  Don't count
	local symbols of a dynamic object.  Handle DT_VER* constants.
	(elf_link_output_extsym): Simplify BFD_ASSERT checking for a
	dynamic object.  Skip indirect symbols from ELF objects.  Remove
	the version name before choosing a hash bucket.  Write out the
	version information if appropriate.
	(elf_link_input_bfd): Check for DYNAMIC, not ET_DYN.
	* bfd-in.h (bfd_elf32_size_dynamic_sections): Update declaration.
	(bfd_elf64_size_dynamic_sections): Likewise.
	* bfd-in2.h: Rebuild.
	* elf-bfd.h (struct elf_link_hash_entry): Add verinfo field.
	Change elf_link_hash_flags to unsigned short.
	(ELF_LINK_HIDDEN): Define.
	(struct elf_obj_tdata): Add fields dynversym_hdr, dynverref_hdr,
	dynverdef_hdr, dynversym_section, dynverdef_section,
	dynverref_section, cverdefs, cverrefs, verdef, verref.
	(elf_dynversym, elf_dynverdef, elf_dynverref): Define.
	(_bfd_elf_swap_verdef_in, _bfd_elf_swap_verdef_out): Declare.
	(_bfd_elf_swap_verdaux_in, _bfd_elf_swap_verdaux_out): Declare.
	(_bfd_elf_swap_verneed_in, _bfd_elf_swap_verneed_out): Declare.
	(_bfd_elf_swap_vernaux_in, _bfd_elf_swap_vernaux_out): Declare.
	(_bfd_elf_swap_versym_in, _bfd_elf_swap_versym_out): Declare.
	(_bfd_elf_slurp_version_tables): Declare.
	* elf.c (_bfd_elf_swap_verdef_in): New function.
	(_bfd_elf_swap_verdef_out): Likewise.
	(_bfd_elf_swap_verdaux_in, _bfd_elf_swap_verdaux_out): Likewise.
	(_bfd_elf_swap_verneed_in, _bfd_elf_swap_verneed_out): Likewise.
	(_bfd_elf_swap_vernaux_in, _bfd_elf_swap_vernaux_out): Likewise.
	(_bfd_elf_swap_versym_in, _bfd_elf_swap_versym_out): Likewise.
	(_bfd_elf_print_private_bfd_data): Add DT_VER* constants.  Print
	version information if there is any.
	(_bfd_elf_link_hash_newfunc): Initialize verinfo field.
	(bfd_section_from_shdr): Handle SHT_GNU_ver* section types.
	(elf_fake_sections): Handle .gnu.version* section names.
	(assign_section_numbers): Handle SHT_GNU_ver* section types.
	(_bfd_elf_slurp_version_tables): New function.
	* elflink.c (_bfd_elf_link_record_dynamic_symbol): Don't include
	version name in string entered in dynamic hash table.
	* elfcode.h: Include fnmatch.h.
	* elf32-i386.c (elf_i386_relocate_section): Handle a dynamic
	symbol which was forced to become local.
	* elf32-m68k.c (elf_m68k_relocate_section): Likewise.
	* elf32-ppc.c (ppc_elf_relocate_section): Likewise.
	* elf32-sparc.c (elf32_sparc_relocate_section): Likewise.
	* elf64-alpha.c (alpha_elf_dynamic_symbol_p): Likewise.
