> Cygwin does not do this on a standard installation.  Is it something you've done

I did use the standard Setup and nothing else...  My $HOME looks fine, too:

$ cd
$ pwd
/home/ANTON
$ getfacl .
# file: .
# owner: ANTON
# group: None
user::rwx
group::---
other::---
default:user::rwx
default:group::r-x
default:other::r-x
$ id
uid=197609(ANTON) gid=197121(None) groups=197121(None),559(Performance Log Users),545(Users),4(INTERACTIVE),66049(CONSOLE LOGON),11(Authenticated Users),15(This Organization),113(Local account),4095(CurrentSession),66048(LOCAL),262154(NTLM Authentication),401408(Medium Mandatory Level)

Whatever is on drive G: was mostly also created by Cygwin -- I was just simply moving stuff from
$HOME to there using tar (IIRC)...  Initially, it was a clean and empty NTFS volume (brand new).
So it was something like:

$ mkdir /cygdrive/g/cygwin

and then for each $stuffdir I wanted moved

$ cd; tar cf - ./$stuffdir | (cd /cygdrive/g/cygwin; tar xvf -)

So, I have no idea why permissions there ended up all perplexed.
But please note that .socket gets created perfectly fine in that directory,
yet the problem occurs when that's a subdirectory, created from under Cygwin!
(and again, all's fine if mkdir for the subdir is done by Windows)

$ cd /cygdrive/g/cygwin
$ getfacl .
# file: .
# owner: ANTON
# group: None
user::rwx
group::---
group:Authenticated Users:rwx
group:SYSTEM:rwx
group:Administrators:rwx
group:Users:r-x
mask::rwx
other::---
default:user::---
default:group::---
default:group:Authenticated Users:rwx
default:group:SYSTEM:rwx
default:group:Administrators:rwx
default:group:Users:r-x
default:mask::rwx
default:other::---
