Once the code has compiled (and there's a similar restriction with Apex). you can skip straight to the definition with ada-mode (C-c C-d). As far as this is concerned, the GNAT project files control switches, name of executable etc, but really as far as this problem is concerned it's just the path that counts; no need to register sources. Or ability, for that matter :-)
