Hi Larry,
I test on various systems and only the RHEL 5 system has this warning. It could be a bogus warning (e.g. the copy constructor is never actually called), but it would be nice if it was not there so we have a clean compile on the common systems.

 Cary -

The oldest gcc I have readily available is 4.4.5, on Debian oldoldstable
(Squeeze LTS).  It does not give the referenced warning.
