from p3. Some shells leave PWD in the environment (old tcsh, ksh at least)

screws nested configures. "unset PWD" is the right answer, except that
Decstation sh doesn't *have* unset.
	Note also that the send-pr build will fail if you have PWD in your
environment, because emacs also (foolishly) trusts it.

	* configure: just set PWD=`pwd` at the top, since Ultrix sh
	doesn't have unset and all success paths (and most error paths)
	out set it anyway. (Note: should change all uses of ${PWD=`pwd`}
	to just ${PWD} to avoid confusion.)
