This is getting a bit OT-  I still plan post an example 
that does not use plink, may hunch is that the problem will still
show up.. we'll see.

A cygwin expect script combined with the cygwin ssh client will do
the same thing.  Honestly I (wrongly) thought the plink example
was going to be easier to follow - sorry.

plink allows you to place the password on the commandline - I know that
is a security issue, but in the real world case, at least I de-crypt
the password and programatically create the plink command line, so I
have no clear text passwords in a script. The reason for sshing to the
localhost (via plink or expect) with *password* authentication, is so
the process running the cron job has full rights to network drives etc.
I could avoid the ssh to localhost, by mapping drives inside yet another
cron wrapper script, but I fear I'll discover other rights the process
won't have, that I have yet to learn about.

Did you notice that the problem I posted is *not* a problem, in the
earlier cygwin snapshot? It is not a problem for the very old version of
cygwin that I'm trying to upgrade either.
