I would like to thank the people kind enough to reply to my
query concerning default copy constructors.  I didn't receive
any mail asking for the answers I received, so I won't bother
to repeat the question here.  The answers I received were
uniformly excellent, and pointed out exactly where I needed
to look to see chapter and verse about default copy constructors.

Thanks to:
