    Problem Text
    This test may fail on implementations because the errno value being
    checked may be overwritten, usually because of an unexpected alarm call.

    There are two problems in test accept 13.

    1. Test case accept 13 fails to save the errno that it will later test, so any
    error that the test case encounters between the return of accept() and the test
    of errno will overwrite the actual errno.

    2. Test case accept 13 also fails to clear alarms set before accept(), so
    that EINTR errors are occuring later in the test.
