Without seeing your exact code, it's hard to say for sure, but Shark8 is probably right that it's a visibility issue. If you're inside AA.Languages.Ada, and you refer to the identifier Ada without any other qualification, then that identifier would refer to your child package, not the top level Ada package. (Standard.Ada would still get you the top-level package.) The error messages are confusing, though. I can understand it, because 99.9999% of the time when a user uses one of the language-defined package names and it isn't defined, it's because they forgot to WITH it; the GNAT people apparently didn't think of this possibility, which is understandable.
