F() vs. F(void) in C vs. C++

I found another difference between C and C++ recently. C++ compiles the code in the following post ok, but C doesn't.

In short, for "typedef struct bar bar;", C views "bar" as an incomplete type, but C++ doesn't.

That doesn't sound right. I think the difference is that C++ doesn't treat that as an array declaration so it doesn't require a complete type.

What is the root cause for the difference?
