    The stream orientation model of Section 2.4.2, "Stream Orientation" of XSH5
    is not aligned with the model described in the ISO C MSE rationale. Base Working
    Group Resolution bwg97-002 has been approved to resolve the discrepancy. Our
    implementation is consistent with the Resolution, but the test suite assumes different
    behavior.

    In particular, XSH5 (p. 33) reads:

    The wide-character output functions convert wide-characters to (possibly multibyte)
    characters and write them to the stream as if they were written by successive calls
    to the fputwc() function. Each conversion occurs as if by a call to the wcrtomb()
    function, with the conversion state described by the stream's own mbstate_t object.

    The Resolution amends the same paragraph to read:

    The wide-character output functions convert wide-characters to (possibly multibyte)
    characters and write them to the stream as if they were written by successive calls
    to the fputwc() function. Each conversion occurs as if by a call to the wcrtomb()
    function, with the conversion state described by the stream's own mbstate_t object,
    except the encoding rule associated with the stream is used instead of the encoding
    rule implied by the LC_CTYPE category of the current locale.

    Another paragraph in the Resolution establishes that "the encoding rule associated with
    a stream cannot be changed once it has been set, except by a successful call to
    freopen(), which clears the encoding rule and resets the orientation to unoriented."

    The following code is typical of the failing and unresolved test cases:


    private void
    ch_t28()
    {
    ....
    ch_setup();

    PRINTIT(wfmt("%.10d %.5hi %.15lo %.3f %.4e %.4g %.4g %.4g %.4g %.4g %.7s
    \n") _ i _ h _ l _ d _ d _ g1 _ g2 _ g3 _ g4 _ g5 _ s); /*1*/

    #if defined (_XOPEN_SOURCE) && TEST_XPG > 3
    wclocale(); /*2*/
    PRINTIT(wfmt("%.3S") _ wcstr); /*3*/
    #endif

    DBUG_VOID_RETURN;
    }

    Line /*1*/ calls wprintf(), setting the orientation of the associated stream to
    "wide-oriented" and the encoding rule to that of the "C" locale.

    Line /*2*/ resets the locale, specifying LC_CTYPE as "VSXWCLOC1". The stream's
    encoding rule is still "C".

    Line /*3*/ calls wprintf() again, expecting the encoding rule to be that of
    "VSXWCLOC1", and an error is set to indicate that a character cannot be decoded.

    Note that the Resolution specifies that "either behavior is deemed
    conforming" pending a future revision of XSH5, so an implementation
    that passes these tests is not necessarily nonconformant.

    We believe that our implementation behaves as the Resolution requires.
    The test suite must not fail correct implementations of the Resolution.

    This is accepted as a fault in the test suite. However, since the number
    of tests affected is quite large this should be addressed by issuing a
    patch rather than by granting a TSD.

    It is recommended that this waiver request is refused.
