[gtkmm] mem_fun arg !

[junk siology net]

ok, during implementing this threaded system i was recommended a few days ago (thanks for that) ive run into this

m_button_df.signal_clicked().connect( SigC::mem_fun(*this, &PSKWindow::getcpuinfo) );

which errors with "mem_fun undeclared in namespace SigC"

also i have to use "SigC" not "sigc" thats in the examples. is this a gcc 3.2.x issue ? i notice the example's code uses no namespace or related lines of code.
