+ * stable. Only structs that have architecture-dependent size are checked by |
+ * this test. These structs use at least one type which differs in size between |
+ * 64-bit and 32-bit (e.g. pointers or long). By convention, we require other |
+ * types to be of consistent size on 32-bit and 64-bit architectures. |
