Quite a lot. And you can't get it on Linux.

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 :-)
