The native build subsitutes a "\" continuation character for that.
That file is evidently supposed to be post-processed with this "sed"
script (after "cpp"), defined as CppSedMagic in "xc/Imake.cf":

sed -e '/^#  *[0-9][0-9]*  *.*$$/d' \
			-e '/^#line  *[0-9][0-9]*  *.*$$/d' \
			-e '/^[ 	]*XCOMM$$/s/XCOMM/#/' \
			-e '/^[		]*XCOMM[^a-zA-Z0-9_]/s/XCOMM/#/' \
			-e '/^[		]*XHASH/s/XHASH/#/' \
			-e '/\@\@$$/s/\@\@$$/\\/'

[That's a <space>, then a <tab> between the brackets.] It looks like
the last line is missing from X11TOOL_UNXCOMM in bsd.x11.mk, plus some
other slight differences.
