Dear Scott and David,

Thanks you both for your help.

I originally ran into this problem a few weeks ago and experimented with
changing 'getopt' to 'getopts' in dacdif, thinking it might just be a
naming issue in cygwin and noticing I had 'getopts' but not 'getopt'. I
forgot to change it back when I revisited the problem. Sorry!

For the record, getopt is in the cygwin package 'util-linux' which isn't
installed by default. After I installed this everything works fine.

Thanks again,

Steve.
