[AUCTeX-devel] Windows install documentation patch

Clears up confusing windows documentation on png support.

Inspired by the line in the documentation "complain to wherever you got your
Emacs from", which along with the rest of the paragraph implies that this
should not be a problem when getting it directly from the auctex website link
to gnu emacs.  Unfortunately this was not the case, the windows gnu emacs
linked to on the auctex site does not have png support compiled in and caused
me to waste hours of time. So my complaint comes with a patch. Also, the web
interface to the auctex cvs crashes when I try to open the "doc" directory, so
not sure if this is the cvs latest version, but it probably is.

 Well, that about is all.  Have fun!
