	(vms_dwarf2_file_time_name, vms_dwarf2_file_size_name)
	(vms_dwarf2_file_name): New functions.
	(vms_file_stats_name): Make it static, add a dirname parameter to
	locally create the full pathname.
	* config/te-vms.h: Add a copyright header.
	Declare the above functions.
	(DWARF2_FILE_TIME_NAME, DWARF2_FILE_SIZE_NAME, DWARF2_FILE_NAME): Use
	the above functions in the definition.
	* makefile.vms (OBJS): Add te-vms.obj.
	(te-vms.obj): Create a specific target.
	* configure.com: Create targ-env.h using a per target value.
	Compile te-vms.c for ia64.
