There is, for ages.  However, you have to run cygserver for that
to work:

  https://cygwin.com/cygwin-ug-net/using-cygserver.html

If cygserver isn't running, the XSI IPC functions return ENOSYS.

Alternatively, convert your tool to using POSIX message queues, those
are using a file backed solution and don't require cygserver.
