+Subject: [PATCH] Bug 5041: Missing Debug::Extra breaks build on hosts with
+ systemd
+
+Master commit 6fa8c66 (i.e. Bug 5016 fix) relied on Debug::Extra added
+by master commit (ccfbe8f) that was not ported to v4. The port of the
+former master commit lacked the required piece of the latter commit.
+
+The problem is invisible on hosts without a systemd package (that Squid
+can find/use) and with Squids explicitly ./configured --without-systemd.
