    Problem Text
    When this test case is run with pseudo-ttys, the O_NOCTTY flag is
    never used when it opens the terminal file.

    The test case initially calls terms_prep() with the request to
    use both the O_RDWR and O_NOCTTY flags. This function will then call
    do_prep() to open the terminal file with the flags passed into the
    "oflags" variable. This variable is used when opening a normal terminal
    device, but is not used when calling openpty(), which is the function
    that opens all pseudo-ttys.

    Because the O_NOCTTY flag is not passed onto openpty(), it opens the
    terminal side without the O_NOCTTY flag. And since the test case had just
    previously created a session leader without a controlling terminal, the
    opening of the terminal side forces it to become the new controlling
    terminal.
    Test Output
    **************************************************************************
    ************************************************************************
    /tset/POSIX.os/devclass/i_ctty/T.i_ctty 4 Failed

    Test Description:
    If general terminal interface supported:
    When a process uses the O_NOCTTY option to open(), the terminal
    shall not become the controlling terminal of the calling process.
    Posix Ref: Component Terminal Interface Assertion 7.1.1.3-05(C)

    Test Strategy:
    CREATE child process
    CHILD process:
    CREATE process session using setsid()
    OPEN and initialise terminal file and loopback file, using O_NOCTTY
    on terminal file
    SET signal action for SIGINT to signal catching function
    WRITE interrupt character to loop_fildes
    VERIFY that calling process did not receive SIGINT

    Test Information:
    process received SIGINT when not expected
