Comment (by nickm):

 Looking at the code more: it seems that clang actually does catch the same
 cases here as gcc does, but that clang does not recognize the same magic
 "/* fall through" comments as gcc.

 Current plan is to disable the warning in 0.3.5 through 0.4.2, but replace
 the fallthrough with an attribute in 043 and later.
