The argument '--' causes premature termination of argument

If OPTS begins with '-', then non-option arguments are treated as
arguments to the option '\1'. This behavior is specific to the GNU
'getopt'. If OPTS begins with '+', or POSIXLY_CORRECT is set in
the environment, then do not permute arguments.

char *const *, but this is inaccurate; if argument permutation is
enabled, the argv array (not the strings it points to) must be

/* This implementation of 'getopt' has three modes for handling
options interspersed with non-option arguments. It can stop
scanning for options at the first non-option argument encountered,
as POSIX specifies. It can continue scanning for options after the
first non-option argument, but permute 'argv' as it goes so that,
after 'getopt' is done, all the options precede all the non-option
arguments and 'optind' points to the first non-option argument.
Or, it can report non-option arguments as if they were arguments to
the option character '\x01'.
The default behavior of 'getopt_long' is to permute the argument list.
When this implementation is used standalone, the default behavior of
'getopt' is to stop at the first non-option argument, but when it is
used as part of GNU libc it also permutes the argument list. In both
cases, setting the environment variable POSIXLY_CORRECT to any value
disables permutation.
If the first character of the OPTSTRING argument to 'getopt' or
'getopt_long' is '+', both functions will stop at the first
non-option argument. If it is '-', both functions will report
non-option arguments as arguments to the option character '\x01'. */

If the caller did not specify anything,

/* Keep a global copy of all internal members of getopt_data. */
REQUIRE_ORDER means don't recognize them as options;
stop option processing when the first non-option is seen.
This is what Unix does.
This mode of operation is selected by either setting the environment
variable POSIXLY_CORRECT, or using `+' as the first character
of the list of option characters.
PERMUTE is the default. We permute the contents of ARGV as we scan,
so that eventually all the non-options are at the end. This allows options
to be given in any order, even with programs that were not written to
expect this.
RETURN_IN_ORDER is an option available to programs that were written
to expect options and other ARGV-elements in any order and that care about
the ordering of the two. We describe each non-option ARGV-element
as if it were the argument of an option with character code 1.
Using `-' as the first character of the list of option characters
selects this mode of operation.
The special argument `--' forces an end of option-scanning regardless
of the value of `ordering'. In the case of RETURN_IN_ORDER, only
`--' can cause `getopt' to return -1 with `optind' != ARGC. */
