        * trans-array.c (gfc_get_array_span): Deal with deferred char
        array components having a TYPE_MAX_VALUE of zero.
        (gfc_array_init_size): Use the hidden string length component
        to build the descriptor dtype.
        (gfc_array_allocate): Remove the erroneous replacement of the
        charlen backend decl with a temporary.
        (gfc_conv_expr_descriptor): Use the ss_info string length in
        the case of deferred character components.
        (gfc_alloc_allocatable_for_assignment): Actually compare the
        string lengths for deferred characters. Make sure that kind > 1
        is handled correctly. Set the span field of the descriptor.
        * trans-intrinsic.c (gfc_conv_intrinsic_len): Remove the stupid
        comment.
