6963 (_cpp_get_fresh_line): Don't need to adjust line for missing newline.
6964 (_cpp_lex_direct): Use linemap_position_for_column.
6965 * c-ppoutput.c (maybe_print_line, print_line): Don't take map
6966 parameter. Instead get it from the line_table global. Adjust callers.
6967 (print): Remove map field. Replace line field to src_line.
6968 (init_pp_output, account_for_newlines, maybe_print_line): Adjust.
6969 (cb_line_change): Use SOURCE_COLUMN. Minor optimizations.
6970 (pp_file_change): Use MAIN_FILE_P since we cannot checked print.map.
6971 Use LAST_SOURCE_LINE_LOCATION to "catch up" after #include.

6973 * c-lex.c (map): Remove static variable, for same reason we removed
6974 cpp_reader's map field.
6975 (cb_line_change, cb_def_pragma, cb_define, cb_undef): Hence we need
