[PATCH] D130058: [Clang] Diagnose ill-formed constant expression when setting a non fixed enum to a value outside the range of the enumeration values

[Mike Hommey via Phabricator via cfe-commits]

Having looked around in the Firefox codebase for cases that now fail to build because of this, and looking at the clarification in DR2338, I wonder if enums in `extern "C"` sections should be treated as if they had an explicit type of `int` as if it were e.g. `enum Foo: int { ... }`.
