I used the Windows Properties dialog on C:\cygwin to add 
'Administrator:Full Control' on my existing cygwin installation (since I 
had done very little personalization, there were no "private" files 
belonging to my unprivileged self to worry about).

This propagated down to all contained objects.

Now the perms/ACLs look a bit more sane.

$ ls -l aatest.exe
-rwxr-x---+ 1 Administrator Users 6144 Mar 20 13:53 aatest.exe

$ getfacl aatest.exe
# file: aatest.exe
# owner: Administrator
# group: Users
user::rwx
group::r-x
group:SYSTEM:rwx
group:Administrators:rwx
mask:rwx
other:---

It's not that anything was noticeably broken -- it's just that things 
looked so WEIRD I didn't really try to DO anything; afraid that I might 
have to wipe out any customizations and start over.  Now, I've been 
involved with cygwin for a long time, but Vista+cygwin gives me the 
creeping heebie-jeebies...or maybe I'm just over-thinking it.
