+This patch uses a "belt & suspenders" approach: either the inclusion of
+<sys/types.h> before the define, or changing the variable name is sufficient,
+but both are used out of precaution.  The patch was developed in-house;
+the changing of the variable name part has been fed upstream and will be
+included in the next version.
