Byte-compiling lisp/emacs-lisp/smie.el in emacs-23 gives the following
warnings:

,----
| In smie-setup:
| smie.el:1536:14:Warning: assignment to free variable
|     `blink-matching-check-function'
| 
| In end of data:
| smie.el:1559:1:Warning: the function `blink-matching-check-mismatch' is not
|     known to be defined.
`----

Indeed blink-matching-check-function and blink-matching-check-mismatch
only exist in the trunk, not in emacs-23.
