Review Response
The second possible interpretation does not seem to take into account
the previous sentence in the same paragraph which states that
"_XOPEN_XCU_VERSION is defined as an integer value indicating the version
of the XCU specification to which the implementation conforms". This
sentence implies that, when the value is greater than equal to 4, the
conformance requirements as set out on Page 1 of the XCU specification
will be met. The XCU specification requires that the implementation
provides the localedef utility and the user portability utilities option.
It seems that this requirement prohibits the setting of, at least,
_POSIX2_LOCALEDEF and _POSIX2_UPE to -1.

It may be possible for a conforming implementation to leave these
constants undefined in <unistd.h>. However, such an implementation
must provide an environment in which a call to sysconf() or the getconf
utility will produce a value other than -1.
