	* tree.c (get_identifier): Use ggc_alloc_string, not obstack_copy0, to
	allocate the string.
	* ggc-simple.c (ggc_mark_tree): Mark the IDENTIFIER_POINTER for an
	IDENTIFIER_NODE.
	* emit-rtl.c (gen_rtx): Don't duplicate any strings passed to this
	function.
	* gengenrtl.c (gendef): Don't let generated functions duplicate
	strings passed to them.
	
	* stmt.c (init_stmt): Add roots for nonlocal_labels,
	nonlocal_goto_handler_slot and nonlocal_goto_stack_level.
	
	* function.h (struct function): Replace the eh-related elements with
	a pointer to a struct eh_function.
	Delete the unused stor-layout elements.
	* function.c (mark_function_chain): Call mark_eh_state instead of
	marking the removed eh specific elements directly.
	Don't mark the removed stor-layout specific elements.
	Mark NONLOCAL_LABELS element.
	(mark_parm_reg_stack_loc): New function.
	(init_function_once): Add root for parm_reg_stack_loc.
	* except.h (struct eh_function): Declare.
	* except.c (mark_eh_state): New function.
	(save_eh_status): Allocate space for eh specific data.
	(restore_eh_status): Free the allocated eh specific data.
	* ggc.h (mark_eh_stack): Don't declare.
	(mark_eh_queue): Don't declare.
	(mark_eh_state): Declare.
	
	* function.h (struct function): Add new element LANGUAGE.
	(save_lang_status): Declare new variable.
	(restore_lang_status): Likewise.
	(mark_lang_status): Likewise.
	* function.c (save_lang_status): Define.
	(restore_lang_status): Likewise.
	(mark_lang_status): Likewise.
	(push_function_context_to): Call language-specific save function.
	(pop_function_context_from): Call language-specific restore function.
	(mark_function_chain): Call language-specific mark function.
	* c-decl.c: Include function.h
	(struct language_function): Renamed from struct c_function.
	Delete NEXT element.
	(c_function_chain): Delete.
	(push_c_function_context): Accept new arg F.
	Don't warn about nested functions being forbidden.
	Don't call push_function_context.
	Don't set up c_function_chain.
	Allocate space for language specific data.
	(pop_c_function_context): Mirror changes in push_c_function_context.
	(mark_c_function_context): New function.
	* c-lang.c (lang_init): Initialize save_lang_status,
	restore_lang_status and mark_lang_status.
	* c-parse.in (nested_function): Warn if pedantic.
	Call {push,pop}_function_context instead of calling C specific
	variants.
	(notype_nested_function): Likewise.
	* c-tree.h (struct function): Declare.
	(push_c_function_context): Update prototype.
	(pop_c_function_context): Likewise.
