  As usual, I don't know what the official manual says. All I know is,
a negative pointer value is total nonsense. Therefore it seems to me that
*any* pointer value assigned to an integer (or long) should be positive. 
So, I would advocate *no* sign extension.
  I would be interested to hear if someone can point out a reference stating
what a compiler should do, or one that explicitly says that this is implemen-
tation dependent.
