           Summary: Implement warning for irrelevant switch statements
           Product: clang
           Version: unspecified
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: enhancement
          Priority: P2
         Component: Semantic Analyzer

MSVC has a nice warning for code like
--
switch (foo) {
}
--
or 
--
switch (foo) {
default:
...
}
--
which would be nice to have in clang (if only to improve portability for
clients who would like their code to be warning free under MSVC).
