You mean, "make TAGS" doesn't run or doesn't create TAGS files in src/
and in lisp/ ?  It does for me.

I'm not sure.  Are we still talking about support for DEFVAR_LISP
etc.?  If so, perhaps you need to say

  C-u M-. make-pointer-invisible RET

?

IOW, when etags finds those DEF* declarations in C files, it tags the
Lisp symbol name, not the C symbol name.  See the regular expressions
we pass to etags: they instruct etags to take the first token that
matches "[^"]+" after an opening parenthesis.  If we want to tag the C
symbol, we need to add another regexp for that.

Other than that, I see no problems in what you get from M-. because
Vmake_pointer_invisible is indeed a C macro defined on that line of
globals.h.  What did you expect to get instead?
