If you're trying to restrict access to certain paths, mount won't help
you here.  mount only maps a DOS-style path to a POSIX one.  Whether or
not a DOS-style path is mounted to a POSIX equivalent, the user can 
always access the path using DOS syntax.  So one can get to the C drive
using "C:\\" in the Cygwin shells or "C:\" at a DOS prompt ("C:/" is also
a valid syntax for Cygwin tools).

If you want security, you need to set the security in the O/S.
Check out setfacl.exe to manipulate permissions from the command line
if that's preferable.
