If EMACS is marked precious, then this is perfectly valid behavior of
autoconf. The question is who is marking it precious (that is, using
AC_ARG_VAR([EMACS]) in some form, so that ./configure --help lists
$EMACS as one of the variables that affects configure operation).
Nothing in the autoconf manual documents the use of EMACS, nor did I
find any evidence of EMACS being used in autoconf source code, so this
is probably something in your configure.ac and not in autoconf itself.
