    Problem Text
    Test 1 expects the uc_link field to be set to something other
    than 0 just by doing a getcontext(). The spec does not say
    that uc_link is set to something by just calling getcontext().
    The uc_link field is to be set by the user to the next context
    to be run after this context is finished. If no next context has
    been set up, it cannot be expected that uc_link would be set to
    other than 0. In the discription for setcontext the spec says:

    "If the uc_link member of the ucontext_t structure pointed to by
    ucp argument is equal to 0, then this context is the main context,
    and the process will exit when this context returns."

    This implies that 0 is a valid value for uc_link.
    Test Output
    TEST CASE: getcontext

    TEST PURPOSE #1
    A successful call to int getcontext(ucontext_t *ucp)
    shall place a pointer to the context that will be
    resumed when the current context returns into the
    uc_link member of the ucontext_t pointed to by ucp and
    return 0.
    TEST: getcontext returns 0
    TEST: Base context put into uc_link
