        PR other/17762
        * lex.l: Include input.h and errors.h
        (lineno): New variable.
        (LINEMAP_POSITION_FOR_COLUMN): Define as noop when USE_MAPPED_LOCATION
        is not defined.
        Set column position with LINEMAP_POSITION_FOR_COLUMN.
        Use error instead of fprintf.
        Set input_location with the value returned by linemap_start_line when
        USE_MAPPED_LOCATION is defined.
        (dump_lex_value): Use LOCATION_LINE.
        * parse.y: Include errors.h.
        Use error and warning instead of fprintf.
        (return): Move exp to rule scope and always set to $2.  Test against
        exp instead of $2.
        (init): Set $$ to $2.
        (print_token): Use LOCATION_LINE.
        * tree1.c (treelang_init): Call treelang_init_decl_processing last.
        Call linemap_add to set input_filename when USE_MAPPED_LOCATION is
        defined.
        (treelang_parse_file): Always start at line one.
        Rename input_filename to main_input_filename when USE_MAPPED_LOCATION is
        defined.
        Leave main_input_filename when done parsing the input.
        (insert_tree_name): Use error instead of fprintf.
        * treetree.c (tree_code_get_expression): Wrap long line.
        (tree_mark_addressable): Use %qD to print out DECLs.
