I agree this is not a helpful warning to have at -Wall, there's no requirement
for the values of an enumeration to have a corresponding enumerator.

I find the "not handled in switch" warning from -Wswitch very useful, but not
the "not in enumerated type" warning, they should be separate.

In any case, the documentation talks about the range of the type while the
actual warning text talks about values not being "in" the enumerated type,
which is not true when the value is within range of the type.
