[AUCTeX] 11.85; preview not rendering jpeg images

[Sivaram Neelakantan]

I tried the builtin example circ.tex and I can't seem to get it to
work.  With png and dvipng as preview-image-type, I got errors saying

error in process sentinel: preview-reraise-error: preview-image-type
setting 'png unsupported by this Emacs

Setting it to jpeg, seems to render some black boxes inline (similar
to what you see in the HELLO file when the appropriate fonts are not
there).  Of course, clicking on the boxes with mouse2/3 gives the
preview options but it refreshes to the same boxes.  This is what I
also see in the *messages* buffer (lots of them).

Error reading JPEG image `(image :file
c:/gnu/elisp/auctex-11.85/preview/circ.prv/tmp4764Dq3/pr3-12.jpeg
:type jpeg :ascent 63)': JPEG parameter struct mismatch: library
thinks size is 464, caller expects 432

Should the jpeg dll be present in the search path for it to render or
is it built into the canonical Emacs 22.2 version?
