From 128c495e509065efe384fba6d986af788f9fbab9 Mon Sep 17 00:00:00 2001 From: Dimitry Andric Date: Wed, 10 Jul 2019 05:57:37 +0000 Subject: [PATCH] Apply a workaround to be able to build clang 8.0.0 headers with clang 3.4.1, which is still in the stable/10 branch. It looks like clang 3.4.1 implements static_asserts by instantiating a temporary static object, and if those are in an anonymous union, it results in "error: anonymous union can only contain non-static data members". To work around this implementation limitation, move the static_asserts in question out of the anonymous unions. This should make building the latest stable/11 from stable/10 possible again.
