+Subject: [PATCH] Use explicit typecast to enum rrdset_flags
+
+specifications say
+An enumerator can be promoted to an integer value. However,
+converting an integer to an enumerator requires an explicit
+cast, and the results are not defined.
+
+Therefore The bitwise OR operation you are performing results
+in an int, which you then attempt to assign to a variable of
+type rrdset_flags without a cast.
+
+Fixes
+| ml/Host.cc:167:9: error: assigning to 'RRDSET_FLAGS' (aka 'rrdset_flags') from incompatible type 'int'
+|         rrdset_flag_set(RS, RRDSET_FLAG_ANOMALY_DETECTION);
+|         ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
