    Problem Text
    This failure was first seen in VST5.2.3A, (i.e the patch A that was released
    for VST 5.2.3.) and has been acknowledged by vst_support.

    The behaviour observed, is consistent with the requirements of XNS Issue 5.
    In this test case, t_accept() succeeds. As a result the state of the
    endpoints specified in t_accept() change. The listening endpoint changes
    from T_INCON to T_IDLE, and the accepting endpoint changes from T_UNBND
    to T_DATAXFER as specified in Table 5-7, Page 37, XNS Issue 5. It may be
    noted that the test recognizes that a call to t_accept() may succeed in
    Unix98 test mode, and need not return [TLOOK]. But it still expects the
    state of the endpoints to remain the same. The test should take into account
    the fact that a successful t_accept() will cause the state of the endpoints
    to change as specified in the state transition table, Table 5-7 Page 37,
    XNS Issue 5.

    In XNS Issue 4, t_accept() is specified to return -1 and set t_errno to TLOOK,
    if there are any incoming T_LISTEN or T_DISCONNECT events. This behaviour was
    relaxed in XNS Issue 5, since there is no need for t_accept() to fail due to
    an unrelated incoming T_LISTEN or T_DISCONNECT event.
    Test Output
    ***********************************************************************
    /tset/XTI.os/cots/accept/T.accept 23 Failed

    Test Description:
    If the implementation supports a connection-oriented transport service
    which supports protocol addresses with a qlen greater than one:
    When a T_LISTEN event that requires immediate attention has
    occurred on fd, then t_accept() returns (int)-1, sets t_errno to
    TLOOK, and the states of the endpoints fd and resfd are not
    changed.
    Note: in UNIX98 test mode the t_accept() call may succeed instead of
    producing a TLOOK error.
    Test Strategy:
    VERIFY that the transport service is of type T_COTS or T_COTS_ORD
    MASTER:

    VERIFY that the transport provider supports a qlen greater than 1
    OBTAIN an endpoint with qlen 2 in T_INCON state using provsetup()
    OPEN a second endpoint using t_open()
    INITIALISE second endpoint using u_provinit()
    SLAVE:
    GENERATE T_LISTEN event on master using listen_ev_s()
    MASTER:
    WAIT for a T_LISTEN event on the endpoint using wait_event()
    ACCEPT first connect request using t_accept() with resfd as second
    endpoint
    VERIFY that t_accept() returned -1 and set t_errno to TLOOK
    VERIFY that t_look() returns T_LISTEN
    VERIFY that the states of the endpoints have not changed

    Test Information:

    For TCP endpoint
    STATE VALUES: expected: 4 (T_INCON), observed: 2 (T_IDLE)
    For TCP endpoint
    STATE VALUES: expected: 1 (T_UNBND), observed: 5 (T_DATAXFER)
