	* coffgen.c (coff_fix_symbol_name, coff_write_symbols): Force
	symbol names into strings table when
	bfd_coff_force_symnames_in_strings is true.

	changes within RS6000COFF_C specific code.
	(coff_swap_scnhdr_out): Use PUT_SCNHDR_NLNNO, PUT_SCNHDR_NRELOC,
	MAX_SCNHDR_NRELOC, and MAX_SCNHDR_NLNNO.
	* reloc.c (bfd_perform_relocation, bfd_install_relocation):
	Extend existing hack on target name.
	* xcofflink.c (XCOFF_XVECP): Extend existing hack on
	target name.
	* coff-tic54x.c (ticof): Keep up to date with new fields
	in bfd_coff_backend_data.
	* config.bfd: Add bfd_powerpc_64_arch to targ_arch and define
	targ_selvecs to include rs6000coff64_vec for rs6000.

	(ppc_change_csect): Align correctly for XCOFF64.
	(ppc_machine): New function, which discards "ppc_machine" line.
	(ppc_tc): Cons for 8 when code is 64 bit.
	(md_apply_fix3): Don't check operand->insert.  Handle 64 bit
	relocations.
	(md_parse_option): Handle -a64 and -a32.
	(ppc_xcoff64): New.
	* config/tc-ppc.h (TARGET_MACH): Define.
	(TARGET_FORMAT): Move to function.
	(SUB_SEGMENT_ALIGN): Use ppc_subseg_align.

	include:
	* include/coff/rs6k64.h: New file.
