Useless typedefs probably produce a warning as they do in gcc:
--
ddunbar at ddunbar2:rt$ cat foo4.c
typedef struct S {
  int x;
};
ddunbar at ddunbar2:rt$ clang -fsyntax-only foo4.c
ddunbar at ddunbar2:rt$ gcc -fsyntax-only foo4.c
foo4.c:3: warning: useless storage class specifier in empty declaration
ddunbar at ddunbar2:rt$
