This patch adds an option for g++ to emit a warning when it sees
   extern "C" { struct foo {}; }
Such empty structures have different sizes in C++ and C modules. Linked
together the modules make the life painful. Supplying -Wempty-c-struct
option tells g++ to warn. Default is not to warn.

Why not warn for C code, too?
