It looks like =C2=ABstring-collate-lessp=C2=BB, when used with the POSIX =
locale,
is equivalent to =C2=ABstring<=C2=BB. The examples I tried out all came u=
p the
same, and [1] (headline =C2=ABLC_COLLATE Category in the POSIX Locale=C2=BB=
) says
the POSIX collation ordering is the same as the ASCII codeset. glibc
adheres to this too (cf. /usr/share/i18n/locales/POSIX).

[1] <http://pubs.opengroup.org/onlinepubs/009695399/basedefs/xbd_chap07.h=
tml#tag_07_03>

In that case the extension to the test case might be better left out.

When I was looking into this yesterday I noticed that glibc ships a
locale definition file that specifies collation according to ISO 14651
(which most language locales derive from), but unfortunately the POSIX
locale doesn=E2=80=99t use that.

Kind regards,
SR
