But the withdrawn POSIX.4 ACL interface proposal does not seem to be supported 
either.

I am on a system that sports both - depending on the underlying filesystem.

BTW: With regard to the NTFS/NFSv4 ACLs, I recently enhanced star to use a more 
compact ACL format in this case.

Here is what the old definition was: 

30 atime=1383676106.725425278
30 ctime=1383676333.651257344
30 mtime=1383676106.725425278
324 
SCHILY.acl.ace=group:daemon:rwx-----------:-------:allow:12,user:root:rwx-----------:-------:allow:0,owner@:--x-----------:-------:deny,owner@:rw-p---A-W-Co-:-------:allow,group@:-wxp----------:-------:deny,group@:r-------------:-------:allow,everyone@:-wxp---A-W-Co-:-------:deny,everyone@:r-----a-R-c--s:-------:allow
23 SCHILY.dev=47775747
17 SCHILY.ino=11
18 SCHILY.nlink=1
27 SCHILY.filetype=regular

and here is the new compact format:

30 atime=1383676106.725425278
30 ctime=1383676333.651257344
30 mtime=1383676106.725425278
186 
SCHILY.acl.ace=group:daemon:rwx::allow:12,user:root:rwx::allow:0,owner@:x::deny,owner@:rwpAWCo::allow,group@:wxp::deny,group@:r::allow,everyone@:wxpAWCo::deny,everyone@:raRcs::allow
23 SCHILY.dev=47775747
17 SCHILY.ino=11
18 SCHILY.nlink=1
27 SCHILY.filetype=regular

that usually fits in a single 512 byte block.
