I am having a problem using the Compose key on my DEC 3100 keyboard as
a META key.  This is in:

GNU Emacs 19.26.1 (alpha-dec-osf) of Sun Sep 18 1994 on reef.cs.jcu.edu.au

on:

% uname -a
OSF1 reef.cs.jcu.edu.au V3.0 347 alpha

Emacs was compiled with DEC's C compiler (cc).  I'm running emacs on
the alpha machine displaying on my DECstation 3100.  We are using the
version of X11 distributed with OSF.  The problem occurs when
different window managers like mwm and twm are used.

To reproduce the problem, invoke the X version of emacs with -q and
type Compose-v to get a M-v command; you have to press the v three
times to get it to work.  The detailed behaviour is:

I type:			this happens:

Compose (hold down)	the keyboard "Compose" light comes on
v			nothing happens
v			the keyboard beeps and the "Compose" light goes out
v			the M-v command is executed by Emacs

If the compose key is kept down, further M-v's can be obtained with
one v per M-v.

As far as I have been able to determine the problem occurs when
compose is used with any character regardless of whether other
modifiers like SHIFT or CONTROL are used. 

This problem first appeared to us in version 19.25 but we haven't
installed any of the versions since 19.19.  The problem *did not*
occur in 19.19.  It may have been triggered by changes in OSF (or the
X11 distributed with OSF) as we *have* changed OSF versions since it
used to work.

Please let me know if there is any further information that would be
useful in tracking this problem down.  Of course, it may be an OSF X11
bug but I'm reporting it to this list first because the response will
be faster than filing an X bug report with DEC and you may have
already heard of the problem and have a fix.

Thanks in advance,
Tony
