enumerate 'identifier' in switch of enum 'identifier' is not handled
The specified enumerate did not have an associated handler in a switch statement, and there was no default label.
The following example causes this warning
enum E { a, b, c };
void func ( E e )
{
switch(e)
{
case a:
case b:
break; // no default label
} // warning, enumerate 'c' not handled
}
