Windows doesn't allow users and groups with the same name.  Cygwin does
in a virtual kind of way.  For instance, create a user "bin" and a group
"bin-grp".  Let's assume they have the following SIDs:

  S-1-5-21-9-8-7-1011 user "bin"
  S-1-5-21-9-8-7-1012 group "bin-grp"

Create passwd and group entries:

  $ mkpasswd -l -u bin >> /etc/passwd
  $ grep '^bin:' /etc/passwd
  
bin:unused_by_nt/2000/xp:1011:513:U-YOUR_PC\bin,S-1-5-21-9-8-7-1011:/home/bin:/bin/bash
  $ mkgroup -l -g bin-grp >> /etc/group
  $ grep '^bin-grp:' /etc/group
  bin-grp:S-1-5-21-9-8-7-1012:1012:

Then edit /etc/passwd so that the primary group for bin is 1012 and
edit /etc/group so that bin-grp is called bin:

  $ grep '^bin:' /etc/passwd
  
bin:unused_by_nt/2000/xp:1011:1012:U-YOUR_PC\bin,S-1-5-21-9-8-7-1011:/home/bin:/bin/bash
  $ grep '^bin-grp:' /etc/group
  bin:S-1-5-21-9-8-7-1012:1012:
