bug#4814: keyboard and system bug with Emacs CVS current through 2009-10-15 on w32

[MON KEY <monkey@sandpframing.com>]

Emacs from CVS current through 2009-10-15 is not correctly interacting
with my system - WinXP Service Pack 3.

There is a low level conflict somewhere related to Emacs'
keyboard/server interaction with the rest of the system.

Specifically, I am experiencing a bug wherein the application Xkeymacs
Version 3.47 :SEE (URL `http://www.cam.hi-ho.ne.jp/oishi/indexen.html')
is no longer able to recognize Emacs application/process nor can it
override Emacs system level interface w/ keyboard.

The current failure has not occurred with _any_ previous Emacs
distributions/builds in the past. Nor have I experienced a conflict of
this sort vis a vis Xkeymacs and _any_ other application. This is
happening on the Emacs side. Lennart and I have already verified that
the bug has been introduced by his build/compilation.

I'm including the config data from the three separate builds - two
verified working one not-working. The only difference that I see are the
compiler and flags. These flags shouldn't affect what is happening w/re
to the way keyboard interaction is failing for the emacsen's interaction
with the rest of the system. The proof is that I have never had this
problem before w/ Emacs or _any_ other application on this machine.
