Problem: 4.2.0 won't compile on AIX 7.1

Browse Source 
Solution: restore inclusion of poll.h if using poll before zmq.h as
it was originally, as AIX redefines the POSIX structures and provides
compatibility macros.
Also add alternative aliases for 32 bit AIX's pollitem struct:
  events -> reqevents
  revents -> rtnevents
