Re: [C++ PATCH] warning about empty extern "C" structures

But not in GNU C:

GCC permits a C structure to have no members:

     struct empty {
     };

 The structure will have size zero.  In C++, empty structures are part
of the language.  G++ treats empty structures as if they had a single
member of type `char'.
Linux kernel, all written in C, has many empty structures. They prevent from introducing safe C++ code.
