neko_default_loader allocate a new loader which does not have a 
hideWindow method. And it's not easy to retreive the current loader 
(since you are outside of a Neko module it would not make sense).

Try setting a callback first, store it into a alloc_root(1) block, and 
use it :

static value *hwindow = NULL;

value set_hide_window( value v ) {
     val_check_function(v,0);
     if( hwindow == NULL ) hwindow = alloc_root(1);
     *hwindow = v;
     return val_null;
}

...

if( hwindow != NULL )
     val_call0(*hwindow);
