enumerate 'identifier' in switch of enum 'identifier' is not explicitly handled by a case label
The specified enumerate did not have an associated handler in a switch statement.
The following example causes this warning
enum E { a, b, c };
void func ( E e )
{
switch(e)
{
case a:
case b:
default:
break;
} // warning, enumerate 'c' not handled by a case label
}
