//    [2010-10-25] added support for non-blocking send/recv operations
//                 - iRCCE_isend(), ..._test(), ..._wait(), ..._push()
//                 - iRCCE_irecv(), ..._test(), ..._wait(), ..._push()
//                 by Carsten Clauss, Chair for Operating Systems,
//                                    RWTH Aachen University
//
//    [2010-11-12] extracted non-blocking code into separate library
//                 by Carsten Scholtes
//
//    [2011-04-19] added wildcard mechanism (iRCCE_ANY_SOURCE) for receiving
//                 a message from an arbitrary remote rank
//                 by Simon Pickartz, Chair for Operating Systems,
//                                    RWTH Aachen University
//
//    [2011-06-27] merged iRCCE_ANY_SOURCE branch with trunk (iRCCE_ANY_LENGTH)
