Comment:

 (In [61718]) 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.

 Fixes #4174.
