message:

cvsntsrv server: warning: cannot write to history file /ADG/CVSROOT/history: Permission denied


On windows only: If file open fails then the file should be checked that it is a 'file' not a 'directory'.  If it's a 
directory then a more appropriate message than 'permission denied' should be returned.
