+Subject: [SV 47995] Ensure forced double-colon rules work with -j.
+
+The fix for SV 44742 had a side-effect that some double-colon targets
+were skipped.  This happens because the "considered" facility assumed
+that all targets would be visited on each walk through the dependency
+graph: we used a bit for considered and toggled it on each pass; if
+we didn't walk the entire graph on every pass the bit would get out
+of sync.  The new behavior after SV 44742 might return early without
+walking the entire graph.  To fix this I changed the considered value
+to an integer which is monotonically increasing: it is then never
+possible to incorrectly determine that a previous pass through the
+graph already considered the current target.
+
+* filedef.h (struct file): make CONSIDERED an unsigned int.
+* main.c (main): No longer need to reset CONSIDERED.
+* remake.c (update_goal_chain): increment CONSIDERED rather than
+inverting it between 0<->1.
+(update_file_1): Reset CONSIDERED to 0 so it's re-considered.
+(check_dep): Ditto.
+* tests/scripts/features/double_colon: Add a regression test.
