Re[2]: Issues with ACL settings after updating to the latest cygwin.dll

Which warning do you mean here?
The "permissions out of order" one. This was not the case before, at least not on my installation, so I don't see how this can be called normal.

Come on, be fair.  The new ACL handling started out early 2015, got a
break when I realized that it doesn't work as is, and then got a new
test phase starting back in September.  Except for minor bugs it seemed
to work rather well. Nobody reported this effect in all the 4 months of
test period.  You don't actually think I wouldn't have fixed it prior
to the release if I had known about it, do you?
2.4.0-1 was released ~3 weeks ago. I had actually upgraded a few days earlier to a TEST version and noticed that a cygwin downloaded exe couldn't be executed but assumed the exe was corrupt and didn't investigate...
Then a few days ago the same thing happened again. Now I'm here.

Anyway, clearly most users are just that: users, and not testers that will install and test TEST versions.

They are not supposed to be modifiable in Explorer.  If you want to
change permissions on a Cygwin ACL, use chmod or setfacl.
Is this a joke?

 Here is the output from icacls /saveacl for some file:
Doh, I'm sorry, but I can't read this format very well.  Can you please
again send the standard icacls output as well as the output from getfacl
of the parent dir and the created file?  I'd like to have this problem
fixed, but I need your help. As I said, it works fine for me and without
being able to reproduce I'm somewhat at a loss.
You can import this by putting it in a textfile and using icacls testfile /restore acl.txt. As I've said before, my Windows is German. icacls output will be localized. Do you really want that?
What I posted is the only portable way to share ACLs.

Here is what's "normal" for Windows if I create a file under a new folder on
 C: in Explorer:

If you don't want POSIX perms, but standard Windows perms, use the "noacl" mount option. See
I guess that is my only option right now.

 Here is what I would expect:
MyUser is in the group Administrators. Given the inherited permissions above
 a Windows-created file should be shown as "-rwxrwxr--+ MyUser

Sorry, can't do that, *unless* you make "Administrators" the primary
group in your user token(*).
Ok, so the group is "None". No big deal.

So what about fixing the permissions like I described?
So the permissions would be "-rwx------+ MyUser None" in Cygwin for a Windows-created file with default ACL.

By using the inherited default ACLs there should be at most 3 additional ACLs (+1 for NULL SID whatever that is doing):
- deny r/w/x for user ("MyUser")
- allow r/w/x for group ("None")
- allow r/w/x for other ("Everyone")

And leaving the inherited ones untouched, right?
But if you scroll up you will see that in my system Cygwin kills the inheritance and I end up with 12 new ACL entries for each file.
