As far as c++ API/ABI goes this is purely additive (it is a change but can't
break anything). Prior to this change comparing two durations for equality
would fail to compile due to the lack of equality operator.
I would expect though that the semantic change from a .NET perspective would
not only be acceptable but actually desired, no?

bq. Review request for qpid, Andrew Stitcher, Alan Conway, Chug Rolke, and
Steve Huston.

bq. Summary
bq. -------
bq.
bq. Fixes ttl overflow on the broker. Added equality operator for
qpid::messaging::Duration (needed it in test and seemed generally valuable).
