I assume this is what CTANGLE produces, in which case your rebuttal of unwind's point is flawed.

However, C99 section 6.9.1 "Function definitions" asserts that

    int f(void) { /* ... */ }

is equivalent to

    int f() { /* ... */ }

Note that this is not true of a function declaration since

    int f();

means function accepting unspecified arguments.

Oh? What language is it? At first glance it looked like C.
