2000-10-09 Dirk Herrmann <D.Herrmann@tu-bs.de>
* print.c (make_print_state, scm_iprin1): Replace SCM_LENGTH with
the appropriate SCM_<type>_LENGTH macro.
(grow_ref_stack): Don't call scm_vector_set_length_x to resize
the print stack.
2000-10-09 Dirk Herrmann <D.Herrmann@tu-bs.de>
* numbers.c (big2str): Avoid redundant copying.
