Hello,

Perhaps this is a bug report, but anyway it can help other people

I don't know if it is an EMACS bug or an X11R4 bug, but I think
that the problem is more towards X11R4 as the problem lies in
the header X11/Xutil.h


The problem :

I'm working on a SUN IPC (SUNOS4.1.0) under X11R4
with an azerty keyboard.

When I want to issue some characters as ( @ ~ \ 5 ~ ),
I must push the so-named "mode_switch" key plus the
corresponding key wher ethe symbol is written to the left.

To do this, I must declare the mode_switch as a modifier
via xmodmap statements.

BUT, in emacs, the mode_switch key (whatever keycode I assign to
this keysym) issue a <ESC> [-1z and I can't issue the famous
characters described earlier.

The solution :

1. While hacking the x11term.c and the X11/Xutil.c, I see that mode_switch
   is considered as a MiscFunction key and NOT as a Modifier Key
   ( see #define IsMiscFunctionKey(keysym) in X11/Xutil.c )


2. I don't like to modify "standard X distribution" , so I modified
   the emacs x11term.c (you can see the diff files lower)

3. With this modification, the Mode_switch key didn't work properly.
   That's because I assigned this modifier to Mod1 and in
   x11term.c , the Mod1 sets the METABIT

4. So I had to undefine mod1 and define mod2 to mode_switch

5. All works well ....
