I did not want to suggest that POSIXLY_CORRECT should always
be set. It's just a way how maintainers can test that there is
a problem with the current code, and that this problem is
fixed by my patch.

Passing -- in the command line will not only stop argument
reordering, it also stops argument parsing which is not
what we need here.
