	* tree-core.h (tree_target_option): Make opts field a pointer to a 
	cl_target_option instead of an instance of the struct.
	* tree.h (TREE_TARGET_OPTION): Return the pointer, not an address of
	the structure.
	* tree.c (make_node_stat ): Allocate a cl_target_option struct for 
	TARGET_OPTION_NODE.
	(copy_node_stat): Allocate and copy struct cl_target_option.
