Re: [Xen-devel] [RFC PATCH 0/4] Add missing default labels to switch statements

I think it is fine to exploit compiler specific checks when available.
However, I don't think we should make any decisions on code correctness
based on the compiler checks that we introduce.
In other words, I think it is a good idea to use -Wswitch-enum if
possible, but it is not a reason for not having default labels in place
as suggested by 16.4. The code should be as correct and safe as
possible, without requiring external compiler-specific checks.
As I said on an answer to Oleksandr, I am not against of having
"default" labels as long as they contain sensible actions.
But this does not really address my point above regarding way to help
the review. Jan is against -Wswitch-enum, and I can understand his
point. So how do you deal with missing item?
