    Problem Text

    The build of the wcstok() failed because of a type mismatch.
    The X/OPEN CAE Specification, System Interfaces and Headers
    Issue 4 defines wcstok() as follows:
    wchar_t *wsctok(wchar_t *ws1, const wchar_t *ws2);

    The ISO/IEC 9899:1990/Amendment 1:1994 draft - Multibyte
    Support Extensions(MSE) as documented in the ISO Working
    Paper SC22/WG14/N325 defines wcstok() as follows:
    wchar_t *wsctok(wchar_t *s1, const wchar_t *s2, wchar_t **ptr);

    This mismatch in function defination was the cause of the
    wsctok build failure. Of course, with wsctok not built, no
    wsctok tests were run.

    Our implementation conforms to MSE as documented in the ISO Working
    Paper SC22/WG14/N325. Since this area of the specification
    is subject to change, we request a permanent interpretation allowing
    the behaviour described in MSE as documented in the
    ISO Working Paper SC22/WG14/N325.

    Review Information

    Review Type TSMA Review

    Completed null
    Status Complete
    Review Recommendation No Resolution Given
    Review Response
    There is a significant issue regarding the change of the function prototype
    for the wcstok() function between the XPG4 definition and the MSE definition.
    Since these two prototypes are incompatible there will be a need for
    implementations to make appropriate use of feature test macros to ensure
    that applications which use the wcstok() function as defined in either of
    these documents will compile.

    It is recommended that this issue is forwarded to the K/RT working group
    for consideration as to the manner in which the MSE extensions should be
    added to an XPG4 conforming system.

    This request should be considered in conjuction with request req.4.2.498.

    It is recommended that this waiver request is refused on the basis that
    the correct prototype for this routine should be visible in the XPG4
    environment.

    Review Resolution No Resolution Given
    Review Conclusion
    Our sepcification is incompatible with the MSE, and therefore there is a
    clear impact on portability. We know that we will align with the MSE in
    the next release, so we know that we are going to make the change to
    the definition that the requestor is currently using. However, the current
    version of the spec "says what it says", so strict conformance would
    indicate that we should reject this request.

    Review Conclusion
    This request is refused.
