It runs and creates the TAGS files.

I'll try to give a more meaningful example. Suppose I'm on line 4818 of
w32term.c and want to know what focus_follows_mouse is and where it is
defined. Typing M-. there prompts me with something like
.../globals.h
#define focus_follows_mouse
bool f_focus_follows_mouse;
How am I supposed to proceed from here?

But I'm in a C file and may not have any a priori knowledge that
focus_follows_mouse is a Lisp variable.

That's precisely what I wanted.

That it goes to the definition of Vmake_pointer_invisible in frame.c
(and never to that in globals.h).
