;; I'm sorry for my bad English.

  I always use gnus-agent to read news and mail on unplugged state.

  But my Internet service provider's news server does not return a Xref 
  header , so nnheader-parse-nov returns nil.
  I don't know the version of INN of my Internet service provider.

  So gnus-agent-expire does not expire articles and remove .overview line.
  After gnus-agent-expire has done , .overview file contains nothing.

  This problem is very serious for me.
  So I create following patch to work with .overview file that does not have
  Xref field.

  I have one question.

  Is this a standard setting that news server returns Xref header ??
  If this is true , I ask my Internet service provider's administrator to 
  return Xref header.
  If this is not always true , pleas apply following patch to gnus-agent.el

I found the following in the "Crosspost Handling" section of the Gnus
manual.  I'd try and talk your News Admin into it.

"To check whether your NNTP server includes the `Xref' header in its
overview files, try `telnet your.nntp.server nntp', `MODE READER' on
`inn' servers, and then say `LIST overview.fmt'.  This may not work,
but if it does, and the last line you get does not read `Xref:full',
then you should shout and whine at your news admin until she includes
the `Xref' header in the overview files."
