 Hhm, I was a leetle involved, too :-)

 The basic idea was indeed Alexandre's IIRC. Extracting the prefix from
 the emacs executable wouldn't always work, eg. in the case of symlinks.
 Thus we simply ask emacs where lisp files are installed.

 For reference: search the 1999 list archive for AC_PREFIX_PROGRAM in
 the subject (early April). The thread started over on the autoconf list.
