That's without ntsec. With ntsec Cygwin reads the Windows ACL and 
attempts to translate it to Unix modes.

The executability of a file (ultimately by Windows) shouldn't depend on
ntsec, although the mode displayed by ls -l does.
With ntsec you can chmod 666 a.exe and it won't be executable (even
by clicking on it), although ls -l with nontsec will show x
(that's an item I didn't understand in Jason't recent mail).

That's the only reason I see, apart from multi-domain. 

Jason raised another issue:

I have not followed setup, so ignore the questions if they are worn out:
- Does setup attempt to control the modes of the files it unpack?
- Do the modes depend on the value of ntsec when setup is run 
  (e.g. inheriting from the directory)?
