Two more (probably easier) ways:
1) Run setup.exe and select "Unix line endings"; then select the "Keep"
mode (switch to the "Partial" view to make sure no packages will get
installed), and complete the installation.  The mounts will be switched.
2) From a bash prompt in /bin, run

PATH="$PATH:." eval "`mount -m | grep ' -t ' | sed 's/ -t / -b /'`"

(Google for "cygwin remount binary").
