Hmm, then try (re-)installing the latest version of the "x-dev" package
from backports.org (version 6.9.0.dfsg.1-5bpo2).  The Xfuncproto.h in
there does include the _X_SENTINEL stuff.

If you don't want to install the newer x-dev package from backports,
then "fixing" Xlib.h by sticking this at the beginning seems fine to me
-- this is the same as the block of code in my version of Xfuncproto.h
in Sid.
