	(lhd_set_decl_assembler_name): Do not append a distinguishing
	number to file-scope internal-linkage declarations for the first

	(make_node_stat): If creating a TRANSLATION_UNIT_DECL, give it
	DECL_UID equal to cur_in_fname.
	(copy_node_stat): Do not change DECL_UID when copying a
	TRANSLATION_UNIT_DECL.
	(build_common_tree_nodes): Adjust next_decl_uid to reserve the
