and for communication between successive calls to `getopt'.
On entry to `getopt', zero means this is the first call; initialize.

non-option elements that the caller should itself scan.

how much of ARGV has been scanned so far. */

_GETOPT_LONG_OPTIONS is a vector of `struct option' terminated by an
element containing a name which is zero.
The field `has_arg' is:
0 if the option does not take an argument,
1 if the option requires an argument,
2 if the option takes an optional argument.
If the field `flag' is nonzero, 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. */
