I've just uploaded this release to
http://www.pogner.demon.co.uk/components/bc/
Changes:
Added Unbounded Collections and Unbounded Ordered Collections.
BC.Support.Bounded, BC.Support.Unbounded subprogram specs were
confused about whether indexing was from 0 (as in the C++) or 1 (in
the Ada). BC.Support.Unbounded.Append(2) had an error when appending
after the first element.
Corrected a misuse of a GNAT compiler "feature" (A procedure and a
protected type entry in the same scope had the same name; you can't
rely on the fact that only entries can have 'Caller applied to resolve
these names).
Added ObjectAda-special versions of the Bag test driver.
