bug#38083: 27.0.50; Deprecation warnings in NS build

[Lars Ingebrigtsen]

I rooted out my Apple laptop (Macos 12.3.1, which is probably the
newest?), and I get the following warnings:

xwidget.c:491:19: warning: variable 'xw' set but not used 
[-Wunused-but-set-variable]
  struct xwidget *xw;
                  ^
xwidget.c:493:23: warning: unused variable 'keycode' [-Wunused-variable]
  int character = -1, keycode = -1;
                      ^
xwidget.c:492:17: warning: variable 'f' set but not used 
[-Wunused-but-set-variable]
  struct frame *f = NULL;
                ^
xwidget.c:493:7: warning: unused variable 'character' [-Wunused-variable]
  int character = -1, keycode = -1;
      ^
xwidget.c:494:7: warning: unused variable 'modifiers' [-Wunused-variable]
  int modifiers = 0;
      ^
and the following deprecation warnings:
