	* vms-lib.c (credat_lo, credat_hi): New fields.
	(vms_read_block): Adjust comments.
	(vms_write_block): New function.
	(_bfd_vms_lib_archive_p): Decode majorid once.  Replace some
	hard-coded values with constants.  Set credat_lo and credat_hi.
	(_bfd_vms_lib_mkarchive): Add argument kind.
	Set ver, mhd_size and type according to kind.
	(_bfd_vms_lib_alpha_mkarchive): New function.
	(struct lib_index): Renamed from struct vms_index
	(lib_index_cmp): Renamed from vms_index_cmp.  Adjusted.
	(get_idxlen): Type of idx argument adjusted.  Add is_elfidx
	argument and handle it.
	(vms_write_index): Adjust argument idx.  Handle elf indexes.
	(_bfd_vms_lib_build_map): Adjust type of arguments modules and res.
	(_bfd_vms_lib_write_archive_contents): Add is_elfidx variable and
	use it.  Handle elf indexes.  Set credat.
