"unwind", "traceback" etc. sound like stack unwinding and traceback in case=
 of exceptions.

Have you tried building the RTS (and an application using the RTS) with pra=
gma Restrictions (No_Exception_Propagation) or pragma Restrictions (No_Exce=
ption_Handlers)? See section 3.1 in the document I linked to. Restriction e=
xception mechanism will of course not provide you with the full Ada excepti=
on mechanism, but may be good enough for your purpose.
