Cygwin includes this version of BSD getopt:
/*      $OpenBSD: getopt_long.c,v 1.16 2004/02/04 18:17:25 millert Exp $        
*/
/*      $NetBSD: getopt_long.c,v 1.15 2002/01/31 22:43:40 tv Exp $      */

$ cat foo.c
#include <stdio.h>
#include "getopt.h"

int main (int argc, char **argv)
{
  int c = 3;
  char *v[4] = {"test", "-r", "foo", NULL};
  struct option l[] = {{NULL}};
  getopt_long (c, v, "r::", l, NULL);

  if (optarg == NULL)
    printf("GNU getopt\n");
  else
    printf("OpenBSD getopt\n");
  return 0;
}
$ ./foo
GNU getopt
$ POSIXLY_CORRECT=1 ./foo
OpenBSD getopt

The same test with gnulib's getopt prints "GNU getopt" both times.

And, as Paul Eggert pointed out, if getopt_long is used to implement pr
- -e, which POSIX requires to take an optional argument, then the behavior
of BSD getopt_long when POSIXLY_CORRECT violates POSIX.

So, unless FreeBSD is more up-to-date than cygwin, the BSD
flavor is still non-compliant to the GNU interface, and the gnulib
configure test is still filtering correctly and providing the
replacement when it is needed.
