- dnl BSD getopt_long uses a way to reset option processing, that is different
- dnl from GNU and Solaris (which copied the GNU behavior). We support both
- dnl GNU and BSD style resetting of getopt_long(), so there's no need to use
- dnl GNU getopt_long() on BSD due to different resetting style.
- dnl
- dnl With getopt_long(), some BSD versions have a bug in handling optional
- dnl arguments. This bug appears only if the environment variable
- dnl POSIXLY_CORRECT has been set, so it shouldn't be too bad in most
- dnl cases; probably most don't have that variable set. But if we actually
- dnl hit this bug, it is a real problem due to our heavy use of optional
- dnl arguments.
- dnl
- dnl According to CVS logs, the bug was introduced in OpenBSD in 2003-09-22
- dnl and copied to FreeBSD in 2004-02-24. It was fixed in both in 2006-09-22,
- dnl so the affected versions shouldn't be popular anymore anyway. NetBSD
- dnl never had this bug. TODO: What about Darwin and others?

- dnl Solaris 10 getopt doesn't handle `+' as a leading character in an
- dnl option string (as of 2005-05-05). We don't use that feature, so this
- dnl is not a problem for us. Thus, the respective test was removed here.
