First hunk:
libc++ doesn't like "using namespace std" in C++11

libproxy/test/get-pac-test.cpp:48:10: error: assigning to 'int' from incompatible type '__bind<int &, sockaddr *, unsigned long>'
                        ret = bind(m_sock, (sockaddr*)&addr, sizeof (struct sockaddr_in));
                              ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Second hunk:
Fix typo.
