	Delete elt NEXT.
	(c_function_chain): Delete.
	(push_c_function_context): New arg F.  Don't warn about nested
	functions here.  Fill LANGUAGE elt of F.  Delete code to update
	c_function_chain.  Don't call push_function_context.
	(pop_c_function_context): New arg F.  Restore from there instead of
	from c_function_chain.  Don't call pop_function_context.  Clear out
	LANGUAGE field of F when done.

	(lang_init): Initialize save_lang_status and restore_lang_status.
	* c-parse.in (nested_function, nested_function_notype): Warn about
	nested functions.  Call push_function_context/pop_function_context

	(free_after_compilation): New function.
	(put_reg_into_stack): Simplify to always call assign_stack_local_1.
