	(ggc_p): Define with value 0.
	(mark_binding_level): New function.
	(init_decl_processing): Add GC roots.
	(mark_c_function_context): New function.
	(lang_mark_false_label_stack): New function.
	(lang_mark_tree): New function.
	(lang_cleanup_tree): New function.
	* c-lang.c: Include "ggc.h".
	(lang_init): Call c_parse_init.
	* c-lex.c: Include "ggc.h".
	(check_linenum): If doing GC, don't copy filenames to permanent
	obstack.
	* c-parse.in: Include "ggc.h".
	(c_parse_init): New function.
	* c-tree.h (c_parse_init, mark_c_function_context): Declare.
	* objc/Make-lang.in (objc-parse.o): Depend on ggc.h.

	* except.c (mark_eh_state): Mark more state.
	* function.c (mark_function_state): Likewise.
	* ggc-simple.c (ggc_alloc_rtvec): Bring in sync with non-gc version.
	(ggc_alloc_string) [GGC_DUMP]: Fix typo.
	* toplev.c (mark_file_stack): New function.
	(compile_file): If doing GC, use ggc_alloc_string on input filename.
