  What, are you saying you also have a file called "foo.sh" that you can't
delete?! ;-)

  Cygwin can't override the permissions enforced by the OS.  It attempts to
/use/ those permissions to model the posix user/group/world model, but if a
file was created outside cygwin (i.e. in windows itself) there's no guarantee
the permissions set on it will make sense in the posix world.  So... if you
actually really have the underlying OS permissions to change the access rights
to a file, chown/chmod will work; if you don't, they won't.

    cheers,
      DaveK
