This email chain makes me wonder if other code paths that are currently 
hidden behind HAVE_GPM that should now be enabled.

I found the following two suspect lines that sound related, but it's 
unclear to me what they're for.  Does anyone know what functionality 
they enable?  (Note: I have some local changes, so my line numbers may 
be slightly off.)

term.c:4253
  tty->mouse_highlight.mouse_face_window = Qnil;

xdisp.c:20783
          gui_clear_window_mouse_face (w);


Additionally, it looks like set-mouse-position and 
set-mouse-pixel-position in frame.c does not behave consistently on TTYs 
if Emacs is compiled with window system support vs without.  I assume 
that should be fixed.
