cvs diff -u does not work after Savannah change

[Lennart Borgman]

I have tried to follow the instructions at 
http://savannah.gnu.org/forum/forum.php?forum_id=4168. I followed the 
instructions "For anonymous working copies" but did not do those under 
"For project member working copy".

I am always doing an anonymous checkout following the current 
instructions on Emas home page (with plink which is/was necessary for 
w32) and that seems fine:

   set CVS_RSH=c:\dl\cvs\plink.exe
   cvs -z3 -d:pserver:address@hidden:/sources/emacs co 
emacs

However when I now try to do

   cvs diff -u

I get

   Empty password used - try 'cvs login' with a real password

  CVS moved to cvs.savannah.[non]gnu.org
  Check http://savannah.gnu.org/forum/forum.php?forum_id=4168 for details.
  Anonymous access over SSH is replaced by the (more efficient) pserver.

and then it hangs. This worked before. Is this a w32 specific problem 
perhaps? Or did I do something wrong?
