To test the limit I wrote the following program:

int main (int argc, char *argv[])
{
  GtkWidget *window;
  GtkWidget *label;
  int i;
  gtk_init (&argc, &argv);
 
  window = gtk_window_new (GTK_WINDOW_TOPLEVEL);
  gtk_container_border_width (GTK_CONTAINER (window), 10);
 
  label = gtk_label_new ("Hello World");
  gtk_container_add (GTK_CONTAINER (window), label);
  gtk_widget_show (label);
  gtk_widget_show (window);
  for (i=0; i<500;i++)
    {
      gdk_pixmap_new(window->window,200,200,-1);
    }
  gtk_main ();
  return 0;
}        

There are no error messages when I run that program on win95 or wine
and I think it uses more than 64KB for bitmaps.
You can load tiles.png using gtk-win32 (I think that is single pixmap
>64KB).
When dividing the big pixmaps freeciv fails allocating some of the small
pixmaps.
