No, I meant under CYGWIN -- why might the file permissions be displayed

Okay, I'm on NTFS. How does NTSEC play into this? In my case, with NTSEC,
the file ownership is "544" while, without NTSEC, the file ownership is
"1897" ("ls -ln" output).

Okay, I'll go along with that. I believe the docs, though, imply that this
happens from 1.1 on. See
http://sources.redhat.com/cygwin/cygwin-ug-net/ntsec.html#NTSEC-RELEASE1.1.
