You need to decide which set of permissions you want to use, POSIX or
Windows, with Cygwin.  If the former, read

<http://cygwin.com/cygwin-ug-net/ntsec.html#ntsec-ids>

and run 'mkpasswd' and 'mkgroup' with the appropriate flags for your
installation to get your user and group in the '/etc/passwd' and '/etc/group'
files.  If you prefer to use Windows permissions only, set the 'noacl' option
for all the mount points for which you want Windows permissions
(http://cygwin.com/cygwin-ug-net/using-utils.html#mount).
