  getopt-gnu: add another test
  
  Ensure that POSIXLY_CORRECT does not interfere with optional argument
  behavior; older BSD implementations botched this.
  
  * tests/test-getopt_long.h (test_getopt_long_posix): New test, to
  guarantee behavior relied on by m4.
  * tests/test-getopt.c (main): Use it.
  * modules/getopt-posix-tests (Depends-on): Add setenv.
  See http://lists.gnu.org/archive/html/bug-m4/2006-09/msg00028.html.
