arguments to the option '\1'. This behavior is specific to the GNU

/* Describe the long-named options requested by the application.
The LONG_OPTIONS argument to getopt_long or getopt_long_only is a vector
of 'struct option' terminated by an element containing a name which is
zero.
The field 'has_arg' is:
no_argument (or 0) if the option does not take an argument,
required_argument (or 1) if the option requires an argument,
optional_argument (or 2) if the option takes an optional argument.
If the field 'flag' is not NULL, it points to a variable that is set
to the value given in the field 'val' when the option is found, but
left unchanged if the option is not found.
To have a long-named option do something other than set an 'int' to
a compiled-in constant, such as set a value from 'optarg', set the
option's 'flag' field to zero and its 'val' field to a nonzero
value (the equivalent single-letter option character, if there is
one). For long options that have a zero 'flag' field, 'getopt'
returns the contents of the 'val' field. */

missing arguments, 'optopt' is set to the option letter, and '?' is
returned.
The OPTS string is a list of characters which are recognized option
letters, optionally followed by colons, specifying that that letter
takes an argument, to be placed in 'optarg'.
If a letter in OPTS is followed by two colons, its argument is
optional. This behavior is specific to the GNU 'getopt'.
The argument '--' causes premature termination of argument
scanning, explicitly telling 'getopt' that there are no more
options.
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. */

According to the C standard, converting UT to T yields an
implementation-defined result or signal for values outside T's
range. However, code that works around this theoretical problem
runs afoul of a compiler bug in Oracle Studio 12.3 x86. See:
http://lists.gnu.org/archive/html/bug-gnulib/2017-04/msg00049.html
