That matches my understanding exactly. Without modification, and
without even having some programmers check whether modifications were
necessary.
So it seems that all discussion of the proximate cause of failure
is irrelevant. If the software had been different, it might have
worked in Ariane 5, or it might not. If it worked, it would
have been purely by accident, since the programmers had never heard
of an Ariane 5 at the time they wrote the software.
