[sigc] Porting libsigc++-1.2 code to libsigc++2.0

[erik_ohrnberger dme net]

I've been searching for information on what I have to change in my code to
migrate it from libsigc++-1.2 to libgigc++-2.0 (as part of the move from
gtkmm-2.0 to gtkmm-2.4)

Any pointers or web references that I can use to help me accomplish this
would be greatly appreciated.

Thanks in advance!

Erik.
