P08184R0: Generalizing the Range-Based For Loop
How can one resolve this reference? It's obviously not a PR number in
GCC Bugzilla.
I found this after some searching:
<http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2016/p0184r0.html>
But it lacks the additional “8”.
Oops, typo. Fixed, along with adjusting the feature-test macro.
If the change is limited to C++17, the adjusted macro should be as well.
