+	* xselect.c: Use signed conversions more consistently (Bug#9498).
+	(selection_data_to_lisp_data): Assume incoming selection data are
+	signed integers, not unsigned.  This is to be consistent with
+	outgoing selection data, which was modified to use signed integers
+	in as part of the fix to Bug#9196 in response to Jan D.'s comment
+	in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
+	expects long, not unsigned long.
