I can't reproduce your problem.  I tried to setup my environment similary,
but it works fine for me.  I guess we need you to examine the situation
further and, if nothing helps, strace output of this chmod.


However, a few hints to your settings:

You don't have /etc/passwd nor /etc/group set up correctly.
Use mkpasswd/mkgroup.

Urgh, you're a masochist, apparently.

Don't do this.  $HOME is not used by Windows, only by Cygwin.  Set it to
a POSIX path (e.g. '/cygdrive/u'), not a Win32 path.  Or let Cygwin do it
by itself.

TMP should probably better be a POSIX path, too.
