+## @file
+#  Null library instance for StackCheckLib which can be included
+#  when a build needs to include stack check functions but does
+#  not want to generate stack check failures. This instance is used
+#  for HOST_APPLICATIONS specifically, as MSVC host applications link
+#  to the C runtime lib that contains the stack cookie definitions, so
+#  must link to a completely null version of this lib, whereas GCC host
+#  host applications do not link to a C runtime lib that contains the stack
+#  cookie definitions, so we must link against our version.
