	* c-decl.c (gettags, pushdecl_function_level): Delete.
	(last_function_parm_vars): Rename last_function_parm_others.
	(current_function_parm_vars): Rename current_function_parm_others.
	(struct c_scope): Rewrite comment explaining this data structure.
	Add names_last, blocks_last, parms_last fields.  Rename
	incomplete_list to incomplete.
	(SCOPE_LIST_APPEND, SCOPE_LIST_CONCAT): New macros.
	(poplevel): Ignore second argument.  No need to nreverse
	anything.  Restructure such that each list is processed
	exactly once.  Use 'const location_t *locus' syntactic sugar
	variable where useful.  Issue unused variable warnings
	ourselves, do not rely on function.c.
	(insert_block, pushdecl, bind_label): Use SCOPE_LIST_APPEND.
	(pushdecl_top_level): Likewise.  Don't call duplicate_decls.
	(implicitly_declare): decl cannot be error_mark_node.
	(undeclared_variable): Manipulate scope structure directly.
	(c_make_fname_decl): Likewise.
	(getdecls, c_init_decl_processing): Fix comment.
	(mark_forward_parm_decls): Use SCOPE_LIST_CONCAT.  No need
	for 'last' variable.
	(grokparms): No need to nreverse parms list.
	(store_parm_decls_newstyle): Set up the parms_last and
	names_last fields of the new scope too.
	(store_parm_decls_oldstyle): Can assume DECL_WEAK is not set
	on parms to begin with; check this under ENABLE_CHECKING.  Set
	up parms_last.
	(check_for_loop_decls): Refer directly to current_scope->tags.
	Use consistent quote style in diagnostics.
	(c_write_global_declarations): The names list is not backward.

	* c-common.h: Don't prototype gettags.
	* c-parse.in: Call poplevel with second argument 0 always.
