I meant if it was compiled against libstdc++ both times, I was curious
whether changing std::tr1::shared_ptr to ceph::shared_ptr would result
in any incompatibility.

I just tried this, and it worked fine (I think because it does not
actually create a new c++ type, but acts like a typedef and just
creates an alias), so I've got no issues with this approach.
