[sigc] missing urls

[Harvey Zimmerman <hlz wheelweb com>]

I was going through the online reference manual and
get a not found for:

http://libsigc.sourceforge.net/libsigc1_2/reference/html/classNode.html
from
http://libsigc.sourceforge.net/libsigc1_2/reference/html/classSlot0-members.html 
and others;

and

http://libsigc.sourceforge.net/libsigc1_2/reference/html/classSignalBase.html
from
http://libsigc.sourceforge.net/libsigc1_2/reference/html/classSignal0-members.html 
and others.


Where may I find these pages?
