From 30b250104d9307e1225031c7fc39b66643265ed1 Mon Sep 17 00:00:00 2001

Subject: [PATCH] Future-proof source for changes in xdemitconf_t
The instances of xdemitconf_t were initialized member by member.
Instead, initialize them to all zero, so we do not have
to update those places each time we introduce a new member.
[jc: minimally fixed by getting rid of a new global]
