	MIPS and LIPS have a similar problem-- that you may not be counting
the same sorts of instructions or logical inferences.  The VAX instruction
to add two integers and the MIPS instruction really don't do the same thing
and similarly a logical inference has the same sort of problem-- even if
you are dealing with the same system (Prolog in this case).  This gets worse
if you start comparing other systems which do their inferences in a different
manner (production systems like YAPS and OPS5 come to mind).

	As usual, benchmarking using LIPS will get you a number with no
solid meaning (as with MIPS).
