The PragmAda Reusable Components contain implementations of both bounded
and unbounded doubly linked lists.

have a look at this:

http://www.ekkehardmorgenstern.de/lists.zip (the archive contains the
specification and body files for the implementation)

It's a doubly-linked listed scheme similar to that that was used in the
AmigaOS kernel (head node, tail node, unlimited node count, and nodes
derived from a simple node record).
It's not multithread-safe yet, but for a basic list scheme that's the most
efficient soluation IMO. ;-)

(btw, off-topic, but I just wanna say that Ada is awesome!! :-) I learnt
much of it in only three days, using the guide for C/C++ programmers on
http://www.adahome.com, the Ada 95 Rationale, and the Ada 95 Reference
manuals -- I didn't think it was that easy when I began, I was really
surprised!! :-) )

Note that Ada Home hasn't been updated for a long time and is seriously 
out of date. Ada Power (www.adapower.com) and Ada World 
(www.adaworld.com) are better sites.
