16183 * c-common.h (pp_dir_change): New declaration.
16184 * cpplib.h (struct cpp_options): Remove working_directory field.
16185 * cppinit.c (cpp_find_main_file, cpp_push_main_file): Merge back to
16186 (cpp_read_main_file): as before 10-01. Call _cpp_stack_file.
16187 Don't handle -fworking_directory here, but in c_common_post_options.
16188 (read_original_directory): Don't back up when done.
16189 Don't clear no-longer used working_directory flag.

16200 (c_common_init): Update accordingly.
16201 (push_command_line_include): Don't cpp_push_main_file.
16202 Do LC_RENAME rather than LC_LEASE to get back to main file.
16203 Compared to pre-10-01 version, inline cpp_rename_to_main_file.
16204 (c_common_parse_file): Call cpp_read_main_file for subsequent main
16205 files, but call finish_options for all files.
16206 * c-opts.c (sanitize_cpp_opts): Don't set cpp_opts->working_directory.
16207 * fix-header.c (read_scan_file): Call cpp_read_main_file instead of
16208 cpp_find_main_file + cpp_push_main_file.
16209 * c-lex.c (fe_file_change): Don't set main_input_filename here.
16210 * opts.c (handle_options): Only set main_input_filename first time.
