+-Wswitch-enum is a bit awkward if a switch statement is intended to\r
+handle just some of the named codes of an enumeration especially, and\r
+leave the rest to the default label.\r
+\r
+We already have -Wall, which enables -Wswitch by default, and per GCC\r
+documentation, "The only difference between -Wswitch and this option\r
+[-Wswitch-enum] is that this option gives a warning about an omitted\r
+enumeration code even if there is a default label."\r
+\r
+Drop -Wswitch-enum to not force listing all named codes of\r
+enumerations in switch statements that have a default label.\r
+\r

+\r
+This will be useful in the next patch.\r
