You can install and use GNAT in your own account without disturbing
anyone elses gcc, and without root privilege. That's enough to at
least try it.

That might work, there may be a better way - check the GNAT
manuals. adainit and adafinal are just made up names (although
possibly emitted by tools) you could change them to be wrapperinit and
wrapperfinal I would guess.
