Whoops!  Missed that.

However, the mounts should be saved *inside* uninstall.bat, using a
Windows path.  :-)
Also, since you're *uninstalling* Cygwin, the mounts should go into a
.bat, not a .sh, with a more suggestive name...

------ BEGIN ------
CYGDIR="`/bin/cygpath -aw /`"

$CYGDIR\\bin\\mount -m > %TEMP%\\restore-mounts.bat
$CYGDIR\\bin\\umount -s -A
$CYGDIR\\bin\\umount -A
copy $CYGDIR\\bin\\cygwin1.dll $CYGDIR\\bin\\regtool.exe %TEMP%
copy $CYGDIR\\ %TEMP%
$CYGDIR\\bin\\rm -rf /
del /s $CYGDIR
%TEMP%\\regtool remove "/HKLM/Software/Cygnus Solutions"
%TEMP%\\regtool remove "/HKCU/Software/Cygnus Solutions"
del %TEMP%\\cygwin1.dll %TEMP%\\regtool.exe
echo Cygwin is now un-installed.
echo To restore the mounts later, run %TEMP%\\restore-mounts.bat
