The most recent version came on two disks. I'm pretty sure the older ones 
did as well.

That extra size is probably just ancient Ada compilers (several were 
included), those would be of essentially no use today. The CDs were curated 
back in the day, with corrections and updates being applied, so the most 
recent version has the best code. Using an older version just gives you 
known and fixed bugs. :-)

I checked a number of different versions of these disks and didn't find 
anything significant on older ones that was omitted from the latest one.
