Both of you are right about PR29606.  The byte-sized strides I do not remember.
 It is one way to go but I do not think that it is the correct one.  I think
that we need a new field in the descriptor or, maybe, a new species of
descriptor. This field could serve two functions:
(i) If present for an intrinsic type, it carries the base stride in bytes; and
(ii) If present for a derived type it carries the size in bytes.
The present size subfield should be used to carry a unique code for the type,
so that classes can be implemented, including abstract classes.
