Having done some more reading, it seems that for [ref] pointers, there 
should be no difference in the marshalling code between:

   [out,ref] int count;
and
   [out,ref] int *count;

so I'll try something at the pre-processor level, perhaps #define-ing a 
macro to * unless pidl is being used.

I'll let you know how it goes.
