    Problem Summary MSF4U.00007 A temporary waiver is requested because because poll does not properly report POLLOUT/POLLIN revents. A workaround is available.
    Problem Text
    A temporary waiver is requested because because poll does not properly
    report POLLOUT/POLLIN revents. A workaround is available.

    The following test cases are being reported:-
    /tset/CAPIsockets/fconnect/fconnect1
    /tset/CAPIbase/fpoll/fpoll26
    /tset/CAPIbase/fpoll/fpoll27
    /tset/CAPIbase/fpoll/fpoll28

    This waiver request is to cover the case where the poll() function does not
    return the POLLOUT/POLLIN flags in revents when the socket is ready for
    writing/reading.

    A workaround is to change the value of POLLWRNORM to 0x0104, and the value
    of POLLRDNORM to 0x0041 in poll.h.

    This failure does not affect program portability because portable applications
    will work correctly with the workaround in place.
