Certainly they were. I doubt they would've had the energy or money,
or inclination, to shop for another, less buggy compiler. Presumably
they spent a big chunk of the budget on the buggy one...

Deep sigh. I rest my case. An Ada implementer who really cared about this
potential market would've delivered compilers that did the right thing
for this group of customers.
