+# Without this %.d rule, ordinary make runs have noise about the recipe for driver--%.o being ill-formed when called on a *.d.

+# Whatever you -include gets called as a target first.
+# One such example is driver--upp-upp--stack-insfirst-allhead.d
+# Without this %.d rule, `make make driver--upp-upp--stack-insfirst-allhead.d` leads to the rule for driver--%.o firing.
+# Though my dumb human eyes don't see the pattern as matching.
