Subject: [PATCH] From Laurens Voerman, "my compiler (VC Express 9) gives some
 warnings (see below) about not being able to generate an assignment operator.
 As those assignment operators are not used and problably should never be
 used, I solved this by creating an private (empty) assingment operator. "

From Robert Osfield, added "return *this;" to Laurens's addition to prevent them generating a warning under gcc...
