  If the C part just sees a set of bits and doesn't care what it
represents, then the fact it's an access to a tagged type is irrelevant,
it could just as well be an integer or string or whatever.  You just
need, on the Ada side, to use attributes to find the size of the
black box object you are sending to C.
