$ CYGPATH=`cygpath -w /`
$ echo $CYGPATH
C:\cygwin
$ CYGPATH=`cygpath -u "$CYGPATH"`
$ echo $CYGPATH
/

What I really want to get is "C:/cygwin" or "/cygdrive/c/cygwin", in my
case.  Look at the weird messages I get from this chmod:

$ chmod -R ug+rwX,o+rX /

Here's an ls of /:

$ ls /
bin              tmp.luke._X_0_-_m_u_l_t_i_w_i_n_d_o_w_
cisrastartx.bat  tmp.luke._c_i_s_r_a_s_t_a_r_t_x_._b_a_t_
cisraxinit.sh    tmp.luke._c_i_s_r_a_x_w_i_n_._s_h_
cygwin.bat       tmp.luke._s_t_a_r_t_x_
cygwin.ico       tmp.luke._s_t_a_r_t_x_-_-_-_c_l_i_p_b_o_a_r_d_0_
etc              tmp.luke._s_t_a_r_t_x_-_-_-_m_u_l_t_i_w_i_n_d_o_w_0_
home             tmp.luke._s_t_a_r_t_x_._b_a_t_
lib              tmp.luke._s_t_a_r_t_x_w_i_n_._s_h_
opt              tmp.luke._x_i_n_i_t_-_-_-_k_b_-_c_l_i_p_b_o_a_r_d_
remap-drives.sh  usr
sbin             var
tmp

(I'm doing this to try to ensure that if a SysAdmin user installs
Cygwin for the actual owner of the machine, the owner will later have
permission to update or even uninstall Cygwin themselves.)
