If you read the contents of /etc/passwd, you'll notice that cygwin uses 
the UID numbers generated by Windows, you just can't go about putting in 
anything you like there. On the other hand 19 is a system reserved UID, 
both in Windows *and* Unix; you may use it but you will be opening a 
security hole big enough to drive the Titanic through your system without 
knocking an iceberg.
