>Description:
        open ("symlink", O_NOFOLLOW, ) returns an errno of EMLINK.
        POSIX1.2008 says it should return ELOOP
        (http://www.opengroup.org/onlinepubs/9699919799/)

        Also the open manual page says that O_NOFOLLOW is a non-standard 
extension,
        seems that it is a standard now.
>How-To-Repeat:
        Build and run the netatalk 2.1 beta release or try the following test 
program.

#include <errno.h>
#include <fcntl.h>

main ()
{
int i = open("foo", O_NOFOLLOW, 0 );
printf ("error %d", errno);
}
