[Bug c++/28236] wrong "control reaches" warning with enums.

[manu at gcc dot gnu dot org]

I don't get this. The enum value can be any integer apart from foo and bar. 
Moreover, since it is undefined, it can be literally anything! So you need a
"default:" case to handle that. 

In the first testcase, without a default case, the function returns (when it
reaches the end) without a value, so the warning is correct.

In the second case, r is not initialized unless __e is X or Y (and if
out-of-range enum values are undefined in C++, __e can be anything!), thus the
warning seems correct as well.

So, is this really a bug?
