    Problem Text
    There seems to be some confusion over the value of _POSIX2_VERSION
    and the return from sysconf(_SC_2_VERSION) for systems supporting the
    historical commands profile.

    The test suite expects sysconf(_SC_2_VERSION) to return the same value
    as _POSIX2_VERSION. This does not seem to be the requirement in XPG4.

    Our system is currently failing the test by having _POSIX2_VERSION
    defined as 199209L and sysconf(_SC_2_VERSION) return -1.

    XSH4 defines the value for _POSIX2_VERSION to be the constant defined in the
    ISO POSIX.2 DIS -- which in the latest draft is currently 199209L .

    The application usage on page 445 states that if the value of
    sysconf(_SC_2_VERSION) is not equal to the value of _POSIX2_VERSION
    it is used to indicate that utilities available via system() and popen()
    might not behave as described in the XCU. This is to be expected for
    systems supporting the historic compatibility commands specification.

    Review Response
    It is noted that the test results suggest that the value of _POSIX2_VERSION
    is set to 999999, rather than 199209L as stated in the above analysis of
    the problem.

    The K/RT interpretation VWG/029/160992 states that _POSIX2_VERSION should
    either be undefined, set to -1 or set to 199209L. In each of these cases
    sysconf(_SC_2_VERSION) must not be more restrictive than the value indicated
    by _POSIX2_VERSION.

    Since _POSIX2_VERSION is not correctly set, it is not possible for this to
    occur. The system should be amended to set _POSIX2_VERSION to -1 or a waiver
    should be granted for a Minor System Fault on the basis that applications are
    not currently expecting to use this feature.

    Review Conclusion
    A Temporary Waiver is granted.
