+// Because the GCC system_header mechanism doesn't work in .c/.cxx compilation
+// units and more important affects the rest of the current include file, the
+// warnings guard is separated into this header file on its own.
+
+// External unicode includes (from icu) cause warning C4668 on Windows.
+// We want to minimize the patches to external headers, so the warnings are
+// disabled here instead of in the header file itself.
