O.K. I see the point. If two versions of a file differ in
specification, Ada is going to warn you about it. The compilation
system by design has to do some sort of time stamping or version
checking to know what's out of date. I can see how that can be
construed as "Configuration Management".
It's just that most of us who have to deal with industrial
strength Configuration Management (it gets really important to
know that the software you're loading in someone's jet is the
exact same identical software that you ran all those verification
tests on!) don't usually consider the "developmental" build
process to fall under "CM". A developmental build - perhaps made
to satisfy yourself that everything still compiles as you are
stirring around in the files - doesn't need to be repeatably
re-built, so it doesn't need to fall under what we usually call
"Configuration Management".
If, on the other hand, you want to make a build which actually
goes into the lab for any sort of "formal" testing, then you need
to know the differences between vsn N and vsn N+1 and you need to
be able to reproduce through some means the exact same image you
gave to the lab. That involves "Configuration Management" and in
that area I don't see Ada (or any language, theoretical or actual)
having much to do with that sort of issue.
I guess it's another one of those "Lets go to the S-OED or
Webster's" issues which is tough to resolve when well meaning and
intelligent people can easily say "around here when we say X we
mean...."
