Thanks for the above suggestion -- it will be part of the final
solution.

Unfortunately, I also have to teach fetchmail that a UID of 18 is
equivalent to 0 (i.e., root) under Cygwin.  Without this "ctl->uid"
above is always 18 and *not* the user's real UID.  It will take me some
time to track this down...  And I hope that the fetchmail maintainer
will accept such a patch...
