Date: Sat, 12 Nov 2022 20:59:19 +0800

Package: cc-mode

Go to line 25895 of xterm.c in Emacs's source code.  Around that
location, there should be:

static int NO_INLINE
x_io_error_quitter (Display *display)
{
  char buf[256];

  snprintf (buf, sizeof buf, "Connection lost to X server '%s'",
	    DisplayString (display));
  x_connection_closed (display, buf, true);

  return 0;
}

There, "x_io_error_quitter" is not fontified as a function!
Thanks.

All that is needed here is to define NO_INLINE as a "noise keyword" in
the C entry in .dir-locals.el.  I'll do this this afternoon/evening.
