2339 (cb_line_change): Set input_line directly, instead of src_line.
2340 (get_non_padding_token): We no longer need to compensate for the
2341 "horrible things" the C++ front-end does with the current line number,

2366 when file_index > 0 (as in multi-file or server compiation).
2367 (finish_options): Change to <built-in> is an LC_ENTER, not LC_RENAME
2368 as this now happens before cpp_push_main_file.
