I have checked in a different proposal, which sets $emacsprefix. I
thought about it and I think it is better this way since we have
possibly different prefixes for emacs and tex,...

I have not implemented the explicit list of locations. The current code
matches ${emacsprefix}/.*/site-lisp which perhaps is good enough. I have
little experience with people modifying the beginning of load-path, is
this common? By the way, is there a reason for checking site-packages in
that AC macro, it is only called for GNU Emacs anyway?

Anyway, I have looked at the other things in aclocal.m4 and there are a
few things I do not like, most notably the relative directories. IMO it
would be better to use the absolute path ${lispdir}/preview than this
relative stuff. We'd get confusing (-ed) questions about this in
auctex-bugs I think.

Another question is if there really is a need for the complicated
TeX-tree path checking which doesn't work here anyway (...reading...)
Oh, I see. Here is the use for our different prefixes. Hmmm. I'll solve
this too, given some time. The easy way is of course to do
AC_PREFIX_PROGRAM(tex)...no, that won't work. This architecture-specific
path component won't get stripped. Bah. I'll figure something out.
