Cygwin X + HP-UX 11.11 + italian keyboard = AltGr not working

[Danilo Turina <danilo dot turina at alcatel-lucent dot com>]

Hello,
	having recently replaced my old keyboard (that had a US layout) with an 
italian one, I'm having a problem with Cygwin X when running HP-UX 
clients: AltGr does not work and this prevents me to use characters like 
"[" "{" "}" "]", etc.

I'm up to date with Cygwin and Cygwin X at the moment ("1.7.9(0.237/5/3) 
2011-03-29 10:10 i686 Cygwin" for Cygwin and "1.10.2.0" for XWin).

These are the steps to reproduce the problem:

	1) start Cygwin X
	2) disable access control ("xhost +")
	3) access via telnet/ssh a HP-UX machine
	4) open an xterm from the HP-UX machine in Cygwin X
	5) in the newly opened xterm try to use AltGr (AltGr + "è" (i.e. the 
key at the right of "P"), should produce "{", while AltGr + Shift + "è" 
should produce "{")
	6) fall on the floor crying in desperation

Notice that when using a client from a Linux machine all works properly.

A googled a lot and found a lot of information but only few of it 
applied (=helped) to my specific case. I tried to mess with xmodmap and 
kbd config files and also with other stuff, but nothing seemed to solve 
the problem.

At the moment I'm using Xming 6.9.0.31 that doesn't seem affected by the 
problem IF I set XKB_DISABLE=1 on the client machine (i.e. HP-UX).

Trying to troubleshoot the problem, I used xev on the HP-UX machine to 
see if the keys were properly recognized and, in effect, they are.
This are xev results for Cygwin X, when I press (and release) AltGr+è 
(thus by trying to get "[") with XKB_DISABLED not set:

If I set XKB_DISABLED=1, I get, instead:

If I try xev on Xming with XKB_DISABLED=1 (where I have no problem at 
all), I get:

One strange thing that I noticed is that if I start Cygwin X by using 
"startxwin" from the Cygwin's command line, I get the following warning 
on screen:

(--) 3 mouse buttons found
(--) Setting autorepeat to delay=500, rate=31
(--) Windows keyboard layout: "00000410" (00000410) "Italian", type 4
(--) Found matching XKB configuration "Italian"
(--) Model = "pc105" Layout = "it" Variant = "none" Options = "none"
Rules = "base" Model = "pc105" Layout = "it" Variant = "none" Options = 
"none"
The XKEYBOARD keymap compiler (xkbcomp) reports:
> Warning:          Type "ONE_LEVEL" has 1 levels, but <RALT> has 2 symbols
>                   Ignoring extra symbols

But that warning is not present in XWin.0.log (attached).

Any suggestion about this problem or about any procedure to diagnose it 
properly?

Thank you,
