    Problem Text
    A permanent interpretation is requested for systems supporting
    XTI on an LP64 architecture supporting both 32-bit and
    64-bit applications.

    XNET Resolution 49-1 states:
    Resolution XNET49-1

    The XNS 4.2 use of "long" , "unsigned long" and (in some cases)
    "size_t" has caused serious problems with upcoming software and
    hardware changes in the market which seek to provide both 32-bit
    and 64-bit environments on the same computer. These developments
    were not foreseen when XNS Issue 4 was published. These problems
    were resolved in XNS Issue 5 by the replacement of these types
    by "t_scalar_t", "t_uscalar_t" and "socklen_t", respectively
    (all of which are defined to be at least 32 bits in length).

    Two problems arise:

    a. Vendors will need to brand such multi-model systems under
    UNIX 95 (which is based on XNS Issue 4) but can not pass
    the UNIX 95 test suite under 64-bit without significant
    implementation hardship.

    b. When UNIX 98 branding (based on XNS Issue 5) becomes
    available, a system so branded will not also be able to
    pass the UNIX 95 test suite and be dual-branded.
    XNET resolves that:

    1. A solution to these problems is necessary in the short
    term.

    2. The solution must be absolutely compatible for existing
    UNIX 95 conformant systems.

    3. The solution must be forward-looking into UNIX 98.

    4. Details of the solution must be publicly available, for
    example via a Corrigendum to the XNS 4.2 specification.
    Approved unanimously.
