acl_extended_file() broken?

[Ethan Benson <erbenson@xxxxxxxxxx>]

I was attempting to compile patched fileutils 4.1.8 for acl
compatibility and finally got it working, except ls -l shows a + for
all files/dirs on acl capable filesystems.  

afaict it uses the libacl function acl_extended_file() to check
whether a file/dir has an actual acl associated, it appears to use
this function correctly so i wrote a test program and found this
function appears to be lying:

eb@dogbert ~$ getfacl /etc/passwd
getfacl: Removing leading '/' from absolute path names
# file: etc/passwd
# owner: root
# group: root
user::rw-
group::r--
other::r--

eb@dogbert ~$ getfattr -m . /etc/passwd
eb@dogbert ~$ ./ckacl /etc/passwd
acl_extended_file returned 1
errno: Success
eb@dogbert ~$ src/fileutils/fileutils-4.1.8acl/src/ls -l /etc/passwd
-rw-r--r--+   1 root     root         1408 05-23 04:36 /etc/passwd
eb@dogbert ~$

am i missing something? the way i read the man page it should return 0:

     The acl_extended_file() function returns 1 if the file or directory
     referred to by the argument path_p is associated with an extended access
     ACL, or if the directory referred to by path_p is associated with a
     default ACL. The function returns 0 if the file has neither an extended
     access ACL nor a default ACL.

eb@dogbert ~$ dpkg -s libattr1 | grep ^Ver
Version: 2.0.8-1

here is my simple test program:

#include <stdio.h>
#include <acl/libacl.h>
#include <errno.h>

int main(int argc, char **argv)
{
     int ret;

     errno = 0;
     if (argc == 2) {
          ret = acl_extended_file(argv[1]);
          printf("acl_extended_file returned %d\n", ret);
          perror("errno");
          return ret;
     }
     else {
          printf("usage: ckacl filename\n");
     return 1;
     }
}
