--- Comment #1 from Richard Smith <richard-llvm at metafoo.co.uk> ---
GCC is wrong. The definitions of g, h, and i are not unprototyped functions.

C11 6.7.6.3 paragraph 14:

"An empty list in a function declarator that is part of a definition of that
function specifies that the function has no parameters. The empty list in a
function declarator that is not part of a definition of that function specifies
that no information about the number or types of the parameters is supplied."

So:

void f(); // unprototyped
void g() {} // equivalent to 'void g(void) {}'
