Ooops... Me neither.

I seem to recall a warning in the *Compile-Log* buffer that
`font-lock-syntactic.keywords' is an obsolete variable.  However, I
can't reproduce it :(

Did I hallucinate?  I had a look: The variable _is_ obsolete as of
font-lock.el:

(make-obsolete-variable 'font-lock-syntactic-keywords
                        'syntax-propertize-function "24.1")

Isn't `make-obsolete-variable` supposed to generate a compiler warning?
Or maybe I found the warning in C-h v font-lock-syntactic-keywords?
I'm confused.

Thanks!
