If this message is not intelligible, I recommend reading
the entire chapter on elaboration issues in the users
guide. Elaboration is certainly a tricky issue, and 
generally you should not turn on -gnatwl unless you know
what you are doing.

We certainly find that helping customers work through
elaboration issues is a significant part of our support
effort, which is why we implemented the static model
of elaboration to try to ameliorate this in the future.
