Subject: [PATCH]      Overhaul of dbmmanage to allow a groups arg (as in
 Apache 1.2)      as well as a comment arg to the add, adduser and update
 cmds.      update allows the user to clear or preserve pw/groups/comment.    
  Fixed a bug in dbmmanage that prevented the check option from      parsing a
 password followed by :group... text.  Corrected the      seed calcualation
 for Win32 systems, and added -lsdbm support.      PR: 3810, 5527
