+Subject: [PATCH] syslogd: fix wrong OPT_locallog flag detection
+
+The OPT_locallog was set on "option_mask32" but checked on local
+"opts" variable. While this flag it's used on multiple places can't be
+has to be used with "option_mask32". Without this change syslogd
+is more-less unusable while no messages are logged locally.
