Summary: - We use a fork of Microsoft's react-native-windows which uses a fork of Facebook's react-native - YGValue.h does not compile with Clang on Windows - This change should fix that - I want to put the change here so that it bubbles back to our fork > https://our.intern.facebook.com/intern/diff/D19656093/ #Changelog: [General][Fixed] Make YGValue.h compile with Clang on Windows Reviewed By: SidharthGuglani Differential Revision: D19717489 fbshipit-source-id: ad867ecaf910bb64a777a06c656a1867bb15484b
