Subject: 	* parser-defs.h (type_stack, type_stack_size,
 type_stack_depth): 	Remove. 	(struct type_stack): New. 	*
 parse.c (type_stack, type_stack_size, type_stack_depth): 	Remove. 
 (type_stack): New global. 	(parse_exp_in_context, check_type_stack_depth)
 	(insert_into_type_stack, insert_type, push_type, push_type_int) 
 (insert_type_address_space, pop_type, pop_type_int) 	(_initialize_parse):
 Update.
