I had a feeling it was something simple like that.  Thanks, Steven! 
That fixes my simple case, but unfortunately, I'm still getting the same 
compilation error with my actual source.  I've cut it down to a 
(relatively) small case, attached.  Interestingly, I tried to eliminate 
the degree dimension from the system, but that caused the minute typedef 
to fail to compile with a 
the_specified_dimension_is_not_representible_in_the_given_system assertion.
