[sigc] Re: ANNOUNCE: libsigc++ 1.9.16 (aka libsigc++ 2.0 beta 5)

[Martin Schulze <martin-ml hippogriff de>]

By the way, I'm currently not able to use my gnome shell account (after
the recent renewal of all passwords) so I can't upload to ftp.gnome. 
org. I've contacted gnome-sysadmin (providing yet another a new
password encrypted in a different manner) and am now waiting for a
response.

Regards,

 Martin
