All this is absolutely correct; but still, if the issue is merely POSIX
conformance, these glibc-based GNU/Linux systems do conform to POSIX,
since the POSIX-conformance document for these systems can state that
the supported locales are merely the single-byte locales. Admittedly this
is legal hairsplitting, but if POSIX compliance is the issue
then one is in legal-hairsplitting mode already....
