Subject: [PATCH] Define global variables only once
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

GCC 10 stopped hiding doubled variable definition. That leads to
linker errors like this:

wmfrog-0.3.1/Src/xutils.h:25: multiple definition of `DisplayDepth'; wmFrog.o:/builddir/build/BUILD/wmfrog-0.3.1/Src/xutils.h:25: first defined here

This patch fixes it.
