(enum gc_used): Document GC_MAYBE_POINTED_TO. (error_at_line): Constify pos argument. (do_typedef): Initialize p->opt field. (get_file_gtfilename): Fix comment typo. (struct walk_type_data): Constify line field. (get_output_file_for_structure): New function. (write_local_func_for_structure): Constify orig_s argument. Use get_output_file_for_structure. (write_func_for_structure): Use get_output_file_for_structure. (INDENT): New define. (dump_pair, dump_type, dump_type_list, dump_typekind) (dump_gc_used, dump_options, dump_fileloc, dump_type_u_s) (dump_type_u_a, dump_type_u_param_struct, dump_everything): New functions. (seen_types): New variable. (main): New variable do_dump. Process "-d" command line option. Call dump_everything if dump requested. From-SVN: r159060
