Specialized function to catch if two enumerations, two selects, or two aggrs

fedex_plus with typedefs, so that they are in fact the same type. TYPEget_-
ctype() is used for most type comparisons and does not consider renamed types
equivalent. This function is called in instances when they should be consi-
dered equivalent. One such case is the generation of duplicate lists.
