Our U2200 compiler used Stream_Element'Size = 9, as that was the native 
character size on that machine (36-bit words). Using 'Size = 8 would have 
required horrific code to access elements.

I don't think there are many modern machines that would be other than 8, 
however.

(And socket I/O probably used 9-bit bytes on that machine as well, although 
I don't remember the details anymore.)
