There have been a couple people with an emacs problem whose symptom is LISP error messages complaining about a bad number of arguments to a function call. Dr. Andrew Mayer cured this problem through a reinstall. Here are the details: http://cygwin.com/ml/cygwin/2003-01/msg00410.html http://cygwin.com/ml/cygwin/2003-01/msg00412.html http://cygwin.com/ml/cygwin/2003-01/msg00421.html His particular problem appears to have been caused by a change to Cygwin that made "ntsec" the default behavior, which resulted in permissions problems that were cured by the reinstall.
