This test intentionally uses a case label that is out-of-range for the switch expression, which is an enumeration type. The problem that lead to the test case was an ICE.

When short enums are on (as they are by default on arm-none-eabi), this test case causes a warning and a spurious failure. Testing with -fshort-enums actually makes the most sense for this test case, as it makes certain that the case value to be out-of-range. So, I've committed this patch, to enable -fshort-enums, but also add -w, so that what we're really testing is that the compiler doesn't crash.

Applied to mainline.
