I had a similar problem with the "sort" program apparently not
functioning and then someone kindly looked at my error output and
pointed out that I should make sure that the CYGWIN bin path was added
to the FRONT of my path as declared in my autoexec.bat
Otherwise, the OS was trying to use the first sort command it found in
the /windoes directory as opposed to the Unix sort command in the Cygwin
package. That took care of my problem and LegOS as worked flawlessly
ever since.
