    Problem Text
    On our implementation we define the identifiers _POSIX2_CHAR_TERM,
    _POSIX2_LOCALEDEF, and _POSIX2_UPE during runtime via sysconf() in
    order to allow flexibility in case we decide to change the value
    at some time in the future.

    In the X/Open CAE Specification, System Interfaces and Headers Issue 4,
    Version 2, under <unistd.h> -- _XOPEN_XCU_VERSION it says "if this
    constant is not defined use the sysconf() function to determine which
    features are supported." And under Constants for Options and Feature
    Groups it says "If these are undefined, the sysconf() function can be
    used to determine whether the feature is provided for a particular
    invocation of the application."

    We believe the standard is unclear about whether these symbolic
    constants must be defined in the header or may be defined at run
    time. We do support _XOPEN_XCU_VERSION=4.

    /tset/POSIX.hdr/misc/unistd_X/T.unistd_X 26 Failed
    Test Description:
    If _XOPEN_XCU_VERSION is greater than or equal to 4:
    The header file contains definitions for the symbolic constants
    _POSIX2_C_BIND, _POSIX2_C_VERSION, _POSIX2_CHAR_TERM,
    _POSIX2_LOCALEDEF and _POSIX2_UPE which each have a value not
    equal to -1.
    Not tested in XPG3 mode.
    Test Strategy:
    COMPILE program including <unistd.h>.
    VERIFY symbolic constant exists using #ifndef.
    VERIFY value of constant is as expected.
    VERIFY there were no compiler errors.

    Review Recommendation No Resolution Given
    Review Response
    PGR4.103 is clear that if _XOPEN_XCU_VERSION is
    set to 4 or greater then the features associated with the listed
    feature groups is enabled (i.e. that functionality is mandatory when
    _XOPEN_XCU_VERSION is set to 4 or later).

    Since an X/Open conforming implementation has always to provide
    the feature. The constants in question have to have a value other
    than -1.

    It is recommended that the waiver be refused.
