New issue 477 by remy.bl...@pobox.com: [Python] Experimental C++ implementation doesn't compile
http://code.google.com/p/protobuf/issues/detail?id=477

What steps will reproduce the problem?
1. Compile Python implementation with PROTOCOL_BUFFERS_PYTHON_IMPLEMENTATION=cpp

What is the expected output? What do you see instead?
 - The expected output is for the Python extension to compile.
 - Instead, compilation throws an error:

google/protobuf/pyext/python-proto2.cc: In function ‘void google::protobuf::python::ReleaseSubMessage(google::protobuf::Message*, const google::protobuf::FieldDescriptor*, google::protobuf::python::CMessage*)’: google/protobuf/pyext/python-proto2.cc:402:57: error: ‘const Reflection’ has no member named ‘ReleaseMessage’

What version of the product are you using? On what operating system?
 - protobuf 2.5.0
 - Gentoo Linux
