turn-on-font-lock is an XEmacs thing, not applicable to GNU
Emacs... (i went looking for a similar defun, but it seems like the
equivilant is (font-lock-mode 1))

Perhaps it is with XEmacs?  I've been trying out GNU Emacs, and this
appears to be a difference in the API:

----
(font-lock-mode &optional ARG)

Toggle Font Lock mode.
With arg, turn Font Lock mode off if and only if arg is a non-positive
number; if arg is nil, toggle Font Lock mode; anything else turns Font
Lock on.
----

So, it seems it should be a numeric argument.

I've got (global-font-lock-mode 1) in my emacs startup file.
According to the help string for g-f-l-m, it takes a numeric argument
as well...

This variable also doesn't seem to be used in gnu/emacs...
