I was expecting a diagnostic. :)
Previously clang would reject this code:
struct __declspec(uuid("12345678-1234-1234-1234-1234567890aB")) S { };
typedef struct _GUID { int x; int y; } GUID;
GUID g = __uuidof(S);
cl.exe accepts and only copies the first 8 bytes, but I'd like to preserve the
original clang behavior. Can we at least check that the sizeof() the user's
type is 16?
