You're right.  I was trying with an out-of-tree build where globals.h
does not get into my way because it's in the build's src directory ;-)

I already did that but it's a slight pain because I also have to remove
all those ../../src/ prefixes from the TAGS file.  But I obviously can
automatize that process if there's no better way.

I'm not sure what you mean.  The source tree's src directory has no
Makefile so I get make: *** No rule to make target `TAGS'.  Stop.  If I
simply invoke make TAGS from its parent directory make TAGS builds Emacs
in-the-tree which is an even greater pain.

See above.

On Windows cmd.exe.  Ever since I created my Emacs tags via

(defun my-shell-etags ()
  (interactive)
  (let ((etags (concat exec-directory "etags.exe *")))
    (let ((default-directory (concat default-directory "src/")))
      (shell-command etags))
    (let ((default-directory (concat default-directory "doc/lispref/")))
      (shell-command etags))
    (let ((default-directory (concat default-directory "doc/emacs/")))
      (shell-command etags))))

from the respective source directory.
