In the cygwin.bat file, put in the following line:
set CYGWIN=ntsec
This will let you get a reasonable semblance of Unix-like security. When
I do this I am able to set/change file permissions.
Hope that this helps.
It seems to:
------------------------------------------------------------------------
---
Administrator@MIMOSA ~
$ touch x
Administrator@MIMOSA ~
$ ls -ln x
-r-xr-xr-x 1 2120 513 973 Nov 22 10:46 x
Administrator@MIMOSA ~
$ chmod 000 x
Administrator@MIMOSA ~
$ ls -ln x
---------- 1 2120 513 973 Nov 22 10:46 x
Administrator@MIMOSA ~
$cp x y
cp: `x.exe' and `y' are the same file
-----------------------------------------------------------------------
Note that if I don't have ntsec set, I get this result:
Administrator@MIMOSA ~
$ touch x
Administrator@MIMOSA ~
$ ls -ln x
-rw-r--r-- 1 500 513 0 Nov 22 10:51 x
Administrator@MIMOSA ~
$ chmod 000 x
Administrator@MIMOSA ~
$ ls -ln x
-r--r--r-- 1 500 513 0 Nov 22 10:51 x
Administrator@MIMOSA ~
$ cp x y

Hello Andrew.
I've read through the FAQ before, but I read it again and still can't
see
the relevance to my case.

I'm running 1.3.5 on Win2K
The cp command doesn't seem to understand permissions correctly. See
following example:
Administrator@SCANNER$ cd /tmp
Administrator@SCANNER$ touch foo
Administrator@SCANNER$ chmod 000 foo
Administrator@SCANNER$ ls -l
total 0
---------- 1 Administ None 0 Nov 21 13:34 foo
Administrator@SCANNER$ cp foo foo1
cp: `foo.exe' and `foo1' are the same file
Doing the same on a Solaris box gets the error:
cp: can not open foo: Permission denied
