+/**
+ * The following macro can help to test the size of a struct at compile
+ * time rather than at run-time. It does not work for all compilers; see
+ * below.
+ *
+ * Depending on the value of 'condition', the following macro is expanded to:
+ * - condition==true:
+ *     an expression containing an array declaration with negative size,
+ *     usually resulting in a compilation error
+ * - condition==false:
+ *     (void) 1; // C statement with no effect
+ *
+ * example:
+ *  COMPILATION_ERROR_IF( sizeof(struct host_sp_queues) != SIZE_OF_HOST_SP_QUEUES_STRUCT);
+ *
+ * verify that the macro indeed triggers a compilation error with your compiler:
+ *  COMPILATION_ERROR_IF( sizeof(struct host_sp_queues) != (sizeof(struct host_sp_queues)+1) );
+ *
+ * Not all compilers will trigger an error with this macro; use a search engine to search for
+ * BUILD_BUG_ON to find other methods.
