--- Comment #2 from Richard Smith <richard-llvm at metafoo.co.uk> ---
In r175660. I've downgraded this from error to warning; we now produce:

<stdin>:2:20: warning: ISO C++11 requires a parenthesized pack declaration to
have a name [-Wanonymous-pack-parens]
void foo(void (*...)(Args))
                   ^


We still reject this case:

template <typename ...Args>
void foo(void (...)(Args));

Since we don't have final wording for core issue 1488 yet, it's not clear
whether this should be valid.
