Actually, the gettext testsuite is buggy. I've now made the testsuite
work with "env POSIXLY_CORRECT=1 make check". So it is not needed any
more to use GNU getopt if the system already has a fully POSIX compliant
getopt() and getopt_long().

If a system does not support the GNU extension which allows to put
option arguments after non-option arguments, it's a choice of the system's
architects. (It has an effect on users, who must tediously port their
shell scripts, reordering arguments in command invocations. But on the
standards side, there's nothing to say against it.) GNU gettext follows
this choice of the platform architects, by using the platform-provided
getopt().
