The reason we have a temporary in the first place is older/broken
C++ compilers. For example, IBM xlC cannot pass std::auto_ptr without
a named temporary.

So what I did is add --std option which allows one to specify the
C++ standard that the generated code should conform to. If you
specify --std c++11, then the temporary is not generated. This
fix is in the repository for the next release.
