Correct? (Cygwin 2.0)

Sat Apr 11 13:25:00 GMT 2015

Hi Corinna,
Reference: https://cygwin.com/ml/cygwin/2015-04/msg00201.html
 - [ANNOUNCEMENT] TEST RELEASE: Cygwin 2.0.0-1
Sorry, Corinna, but I have to ask: will this be the correct behaviour of Cygwin
from now on? ... because I am very much surprised ...
Is there anything I can do (settings directory?) ... to "improve" on what I am
experiencing now?
I create a file (called aap), do not modify its properties (chmod), and then it
turns out that the properties have changed ... Surprise!
Regards,
Henri
 - reinstalled Cygwin, selected Cygwin 2.0
 - using an UNelevated bash shell
 - touch aap
 - chmod -x aap # afterwards the write-bit turns out to be set for group None!
 - chmod -w aap # does not help! (no modification)
