Another part of getting slime to work with xeamcs...
Slime will highlight Lisp code so that reader conditionals are
highlighted differently if they are enabled are not. From what I can
tell (I use lazy-shot), font-lock runs over a portion of the file.
Sometimes this portion stops in the middle of a form that is
conditionalized by some reader conditional:
#-foo
(defun bar ()
<long function>
<font-lock region end here>
<more function>
)
For emacs, slime has a hook to extend the font-lock region.
Is it possible to do something similar with xemacs?

If the name of the hook variable starts with jit-lock-, probably no.
Not yet. jit-lock is a complete rewrite of the internals of font-lock
which hasn't been ported yet.
There is a global hook, font-lock-after-fontify-buffer-hook. There
may also be specific hooks for the lazy-* libraries, but I know very
little about them.
lazy-shot has a lot of hair, maybe there's something in there. But
it's not a hook, lazy-shot defines no hooks.

Slime adds a function to the hook font-lock-extend-region-functions.

I obviously don't know how this all works, but looking at the comments
before font-lock-fontify-buffer in font-lock.el seems to indicate I
could change change font-lock-fontify-region-function to some new
function that would extend the region as needed and then call the old
font-lock-fontify-region-function.
Does that make sense?

... you're a very brave man. :-) Actually, it's probably not that
horrible, but you do need to figure out how to detect that extending
the region needs to be done.

Yes. It may not be very easy, feel free to ask for help if you get a
little stuck; it might not be too hard, either. :-)

Fortunately, slime already provides a function for that. Just need to
figure out how to get that function called and run the real font-lock
function appropriately on the new region. And, most importantly, how to
hook it into font-lock, per the comments. I, frankly, can't really
quite parse the comments, but it looks possible.
This is all kind of fun, but in many ways, it's rather tedious. I could
just keep using the older version of slime that was working fine, but
then I won't ever get bug fixes or cool new features. Or I could switch
to emacs, but decades of cruft in my .xemacs config would have to be
redone, which is not fun. Or try to fix these things.
Ugh.:-)
