No, it's a collision of an internal flag with an official open(2) flag from fcntl.h, used by grep in this case. I changed the way the internal flag is used so it doesn't collide with fcntl.h flags ever, even if we add some more. I uploaded new snapshots for testing to https://cygwin.com/snapshots/ Please give them a try.
