	* vms-alpha.c (struct vms_private_data_struct): Add
	transfer_address field.  Remove unused dst_info field.
	(alpha_vms_write_exec): Use transfer_address.
	(_bfd_vms_write_egsd): Add a comment about LIB$INITIALIZE.
	(alpha_vms_bfd_final_link): Set transfer_address.

	* scripttempl/alphavms.sc: Add comments. Move $LINK$ to the
	readonly output-section. Handle LIB$INITIALIZE and sections
	created by gcc.
