See the following for the full details:

    http://cygwin.com/ml/cygwin/2002-11/msg00136.html

The Cygwin PostgreSQL and KDE communities seem to be happy with the
above.  Would you be willing to accept such a patch into cygipc CVS?

If so, then please let me know because I just found some more places

like to gauge your interest before pursuing this further.

Thanks,
Jason
