The machine is a 4D/70.  Neither the porting guide nor the man page
mentions that the function is only implemented on the GT (if indeed
this is the case), and in fact the porting guide says you should use
the newer routines because "your code will be more portable" and that
"on the GT and future products, the new subroutines will run up to 10
times faster than their old counterparts".
