[Gerald Pfeifer]

   commit 951415b602743af897371e077fb47f56f6461dd7
   Author: Alexandre Julliard <julliard at winehq.org>

   winex11: Store the client window in the window data again, now that it 
   can be accessed from all threads.

causes a compiler warning about an unused variable in GCC 4.8.0,
and indeed with SONAME_LIBXCOMPOSITE not set we need the patch 
below.
