Well, maybe my installation is hosed then.  I have installed for all 
users, but mount -m returns

mount -f -s -b "C:/cygwin/usr/X11R6/lib/X11/fonts" 
"/usr/X11R6/lib/X11/fonts"
mount -f -s -b "C:/cygwin/bin" "/usr/bin"
mount -f -s -b "C:/cygwin/lib" "/usr/lib"
mount -f -s -b "C:/cygwin" "/"
mount -u -b --change-cygdrive-prefix "/cygdrive"
mount -s -b --change-cygdrive-prefix "/"

so...

mount -m | awk -F '"' '/--change-cygdrive-prefix/ { print $2 }'

results in

/cygdrive
/


so, I can see that the grep is not needed, but since there is more than 
one output line, tail, head or the like
would be needed,  no?
