        (do_define): Don't play with put_out_comments.
        (cpp_push_buffer): Initialize ->mark to -1.
        (cpp_buf_line_and_col): Just read out the values in the buffer

        unless it's necessary.

        * cpplib.h (parse_marker): Removed.
        (struct cpp_buffer): Line_base is now an unsigned char *; add

        * cppinit.c: Instead of one pending list, keep separate lists
        for each category of pending option: -D/-U, -A, -include,
        -imacros.  Move the four partial include-path lists into the
        pending block.  Use head and tail pointers so we don't ever
        have to reverse the lists.

        (cpp_start_read): Break out blocks of code to their own
        functions: install_predefs and initialize_dependency_output.
        Use path_include for C_INCLUDE_PATH and friends as well as
        CPATH.  Remove include_defaults gunk.  Warn about the
