The "group" and "other" entries are surprising (to me), but maybe that's not 
important.  On my system I have:

$ cd

$ pwd
/home/kbrown

$ getfacl .
# file: .
# owner: kbrown
# group: None
user::rwx
group::r-x
other::r-x
default:user::rwx
default:group::r-x
default:other::r-x

At this point the permissions on /cygdrive/g/cygwin are influenced by the ACL on 
/cygdrive/g.  What I would typically do in this situation is

   getfacl ~ | setfacl -f - /cygdrive/g/cygwin

That way I'm sure I won't have any surprises with permissions when working in 
/cygdrive/g/cygwin.  Do you want to try that and see if it makes a difference?
