The cygipc package is deprecated for 10 years now.  The functionality
has been taken over by cygserver, see the Cygwin User's Guide:
http://cygwin.com/cygwin-ug-net/using-cygserver.html

Apart from that, Cygwin comes with POSIX IPC functions, which don't
require runing cygserver like the XSI functions do.  See, for instance
http://linux.die.net/man/3/sem_open and friends.
