  Message : GN: Enable more MSVS warnings. Some warnings were enabled only in standalone builds. Enabling them in the GN config will prevent standalone build breakage and also make some potentially harmful warnings more visible to non-Windows devs. BUG=angleproject:1449 Change-Id: I11fe9bac957864d37af37b3860a22fcbd91946ac Reviewed-on: https://chromium-review.googlesource.com/360961 Reviewed-by: Geoff Lang <geofflang@chromium.org> Reviewed-by: Olli Etuaho <oetuaho@nvidia.com> Commit-Queue: Jamie Madill <jmadill@chromium.org>
