Windows NT and 95, by default, have very different permission layouts
from UNIX.  SO, only the 'r' option of chmod (chmod +r foo) really has
any meaning.

On Windows NT, however, if the CYGWIN environment variable contains
'ntsec' then you can get UNIX-like permissions on NTFS drives.  Using
the somewhat deprecated 'ntea' allows you to get UNIX-like permissions
on NTFS and FAT drives but a huge (very hard to delete) file is created
on FAT drives when you do this.

On Windows 95, there are no alternatives.  You have to be content with
twiddling 'chmod -r'.

So, if you can use CYGWIN=ntsec then that's the best solution.  It turns
on all sorts of UNIX-like security in Cygwin.

Otherwise, you're right, 'chmod' doesn't do much.
