Ah thanks a lot!
I changed to this because my-wacky-syntax-table was nil

(setq my-wacky-syntax-table (make-syntax-table))
(modify-syntax-entry ?_ "w" my-wacky-syntax-table)

(defun get-autoconf-word ()
  (interactive)
  (message "%s"
           (with-syntax-table my-wacky-syntax-table
             (thing-at-point 'word))))

But it works :)

About Info I also thought about "g", but what "g" does is just jump in
the right section, if I do

M-: RET (Info-goto-node "Autoconf")
from a info buffer where I see the entry "Autoconf"

I get:
byte-code: No such node or anchor: Autoconf
