The following code produces a "declaration does not declare anything" warning.

Stripped test case from /usr/include/bits/pthreadtypes.h (linux+glibc+NPTL)

typedef union
{
  struct __pthread_mutex_s
  {
    union {
        int a;
        double b;
    };
  } __data;
  char c;
} pthread_mutex_t;

the error is generated in ParseDecl.cpp (diag::w_no_declarators)
