    Problem Summary TIN4W.00006 A non-alignment between the reference code and its specification is under investigation.
    Problem Text
    The reference implementation (i.e. The X11 code provided by TOG) being
    tested is not in line with the standard specification for this X11
    function as defined in the "X Toolkit Intrinsics - C Language
    Interface".
    The assertion being tested is in line with the standard specification
    but the behavior of this function is not in line with the specification.

    Either the X11 reference implementation is at fault, or the
    Specification needs to be aligned with the reference implemenation. It
    is our understanding that X11R6.1 is no longer supported by TOG,
    hence we request this waiver be granted a Permanent Interpretation.

    Section 6.2 of the "X Toolkit Intrinsics - C Language Interface" states:

    "If the geometry manager returns XtGeometryDone, the change has been approved
    and actually has been done. In this case, XtMakeGeometryRequest does no
    configuring and returns XtGeometryYes. XtMakeGeometryRequest never returns
    XtGeometryDone."

    The problem here is that _XtMakeGeometryRequest() is returning "XtGeometryDone"
    when it should never be. XtMakeResizeRequest() calls _XtMakeGeometryRequest().

    Please see the sample code below for an explanation as to why the test
    purpose if failing.

    Review Recommendation No Resolution Given
    Review Response
    A non-alignment between the reference code and its specification is
    under investigation. Thus it is recommended that a Temporary
    Interpretation be granted for this test while it remains subject to review.
    If a change to the specification results from the conclusion of this
    investigation, then this Temporary Interpretation will be converted
    to a Permanent Waiver. Otherwise this Temporary Interpretation will
    be converted to a Temporary Waiver (Minor System Fault)

    Note that this TIN may only be applied for VSW5.0.0. In VSW5.0.1 the
    XT_COVERAGE configuration variable may be used to surpress this test.
