Control symbol exports using -fvisibility
On systems using GCC 4.0 or newer which support symbol visibility in shared
libraries, use -fvisibility=hidden and only export explict API functions
defined in zmq.cpp. We do not enable -fvisibility on MinGW since this uses a
separate mechanism (__declspec).
