Milestone:  Boost 1.43.0             |   Component:  None

-------------------------------------+--------------------------------------
 At several places in the ptr_container tests, we have the following
 pattern:

   void f(const std::auto_ptr<int> &);
   void g() {
     f(std::auto_ptr<int>(new int(5)));
   }

 This is code is ill-formed in C++98/03, because the compiler is required
 to check there there exits a copy constructor that would be able to make a
 copy of the auto_ptr before binding it to a reference, even if that copy
 won't actually be made. Not all compilers diagnose this error, but Clang
 and EDG in strict mode do diagnose the problem.

 The attached patch fixes the issue.
