I'm missing here what is actually produced. Nothing? or the unmodified è?

This is perfectly normal for people having to deal with XKB :-)

I think a solution is contained in this old mailing list post [1], use
XKB_DISABLE=1 and adjust the keyboard map so that AltGr is Mode_switch and the
keys have the expected mapping in group 2, activated via Mode_switch.
Note that just reassigning AltGr to Mode_switch is not enough, you'll need to
remap appropriately the keys which generate different characters with AltGr
e.g. something like:
xmodmap -e "clear mod5"
xmodmap -e "clear mod3"
xmodmap -e "keycode 113 = Mode_switch Multi_key"
xmodmap -e "add mod3 = Mode_switch"
xmodmap -e "keycode 34 = egrave eacute bracketleft braceleft"
(and so on for the other keys which need to generate different characters with
AltGr)
I can't test this, because I don't have access to a HP-UX machine.

It's kind of hard to know how to interpret these results since I don't know
what XKB_DISABLED=1 actually does.

I think this is normal, if a little odd. Warnings from xkbocmp are written to
stdout, but not written to the log.
