2808 (cb_line_change): Set input_line directly, instead of src_line.
2809 (get_non_padding_token): We no longer need to compensate for the
2810 "horrible things" the C++ front-end does with the current line number,
2812 * cpplib.c (_cpp_pop_buffer): Do generate a _cpp_do_file_change
2813 callback even when popping the main file.

2835 when file_index > 0 (as in multi-file or server compiation).
2836 (finish_options): Change to <built-in> is an LC_ENTER, not LC_RENAME
2837 as this now happens before cpp_push_main_file.
2838 (push_command_line_include): When done with options, pass LC_LEAVE
2839 instead of LC_RENAME to cpp_change_file and finally cpp_push_main_file.
