 This should be documented, though; I'll make a patch.

Synopsis: [ABI] Empty structs have zero size in C, but not in C++

State-Changed-Why:
    Not a bug.
    
    Empty structs in C are a GCC extension, and were defined a long
    time ago to be defined as empty size.
    
    Empty structs in C++ are defined by ISO to be size one.
    
    "Don't do that."
