Bug#815495: zeromq3: FTBFS on kFreeBSD: 'xucred cred' has incomplete type

[Aaron M. Ucko]

Source: zeromq3
Version: 4.1.4-3
Severity: important
Justification: fails to build from source (but built successfully in the past)

Builds of zeromq3 for kFreeBSD are now failing with

  src/ipc_listener.cpp: In member function 'bool 
zmq::ipc_listener_t::filter(zmq::fd_t)':
  src/ipc_listener.cpp:263:19: error: aggregate 
'zmq::ipc_listener_t::filter(zmq::fd_t)::xucred cred' has incomplete type and 
cannot be defined
       struct xucred cred;
                     ^
  src/ipc_listener.cpp:268:28: error: 'XUCRED_VERSION' was not declared in this 
scope
       if (cred.cr_version != XUCRED_VERSION)
                              ^
  Makefile:2465: recipe for target 'src/libzmq_la-ipc_listener.lo' failed
  make[2]: *** [src/libzmq_la-ipc_listener.lo] Error 1

Could you please take a look?

Thanks!
