It pobably has stayed there because the recommendation is when you don't 
implement the multiplication and the division in assembler, please at least 
implement d2*+, the support primitive.  And I'm sure this d2*+ has been 
tested in the context it is supposed to be used, and worked there 
(multiplication).  It's just that if you use it for general purpose stuff, 
it won't work.
