1572 * cpplib.c: \r (one character) indicates backslash
1573 newline, not \\\n (two characters). It cannot appear in the

1601 (cpp_get_token): Break out string parsing code to
1602 parse_string. Use skip_comment for CHILL comments too. Use
1603 copy_comment for put_out_comments instead of dinking with

1605 unless it's necessary.
1607 * cpplib.h (parse_marker): Removed.

1679 (append_include_chain): Brought over from cppfiles.c. Mark
1680 dirs as system include dirs if and only if appending to
1681 system include path. If opts->verbose, print a notice when a

1703 (actual_directory): Set x->sysp from
1704 CPP_BUFFER (pfile)->system_header_p so that one system header
1705 may include another with "".
