Yes.

Debian packaging is at:
git://anonscm.debian.org/pkg-xorg/app/xinit

Maybe
---a/startx.cpp
+++b/startx.cpp
-#ifdef __linux__
+#if defined(__linux__) && defined(HAVE_SYSTEMD)

and add a stanza to configure.ac that will check for presence of the
systemd development stuff OR --with-systemd, and if detected will add
-DHAVE_SYSTEMD to CPP_FILES_FLAGS.

(I could probably add that and see if upstream will take it...)

Or, perhaps it would be better to add a runtime check such that if logind
is running, that stuff happens.

It's a snippet of makefile, presumably included somehow or other. The
logic there seems obvious to me:

sed rules: delete lines begining with "# " and a number, or "#line"
directives; change XCOMM/XHASH to # (as imake does); and apparently
change "@@$$" to "\".

SUFFIXES and below:
let "make filename" create filename from filename.cpp by running this:
cpp ${TRADITIONALCPPFLAGS} ${CPP_FILES_FLAGS} filename.cpp | \
    sed -e .... >filename
