Hi,
	I recently upgraded to Scheme 7.1 (beta) on our HP9000/350's
and 835's.  It seems to work fine, except that the debugger no longer
functions under gnuemacs; it prints some messages and hangs until you
exit the debug REPL.  The mode line flag doesn't change either.  I'm
using gnuemacs 18.55 and xscheme.el with the following header:

    ;;; $Header: xscheme.el,v 1.23 89/04/28 22:59:40 GMT cph Rel $

This version of xscheme.el worked fine with the alpha version of 7.1 I
picked up off zurich last spring....

A transcript follows: I get similar results on the 3xx and 8xx
machines (using compiled runtime from the distribution in both cases).

Any help would be appreciated.
