| Make `window-system' into a keyboard-local variable (rather than
| frame-local as done originally by multi-tty).
| 
| * startup.el (window-system): Remove.  Don't make it frame-local.
| 
| * keyboard.h (struct kboard): Add Vwindow_system.
| * keyboard.c (init_kboard): Set a default for Vwindow_system.
| (mark_kboards): Mark Vwindow_system.
| 
| * dispnew.c (syms_of_display) <window-system>: Declare terminal-local.
| (init_display): Don't set the obsolete `window-system' frame-param.
| 
| * xterm.c (x_term_init):
| * w32term.c (w32_create_terminal):
| * term.c (init_tty): Set Vwindow_system.
| * macterm.c (mac_create_terminal): Set a keyboard (missing piece of the
| multi-tty merge maybe?), copied from w32term.c.  Set Vwindow_system.
| 
| * xfns.c (Fx_create_frame, x_create_tip_frame):
| * w32fns.c (Fx_create_frame, x_create_tip_frame):
| * macfns.c (Fx_create_frame):
| Don't set the obsolete `window-system' frame-param.
| 
| * frame.h (Qwindow_system): Remove.
| * frame.c (Qwindow_system): Remove.  In `syms_of_frame' as well.
| (Fmake_terminal_frame): Don't set obsolete `window-system' frame-param.
`----

After window-system is changed from frame-local to terminal-local
variable, since macosx doesn't support MULTI_KBOARD, it looks like the
window-system misses a chance to be properly set.(leaving it as t by
default) I doubt other platforms that not yet support MULTI_KBOARD could
have a similar problem.
