Firstly, this list is about development *of* gtk+, not *with* gtk+.  
Please direct these questions at gtk-list or gtk-app-devel-list.

Secondly, gtk+ 1.2 is old, obsolete, deprecated, and unsupported.  The 
function you want to call exists in gtk+ 2.x, not gtk+ 1.x.
http://developer.gnome.org/doc/API/2.0/gtk/GtkWindow.html#id2959364

To replicate this function call in gtk+ 1.2, you'd have to do

   focus_widget = window->focus_widget;

this means that the compiler is using the implicit type for the 
function since it found no prototype, and the implicit type (int) does 
not match how it is being used.  this is your first clue.

the undefined reference means that the linker can't find the function.

use gtk+ 2.x.
