+ * Macro to flag a compile time assertion. It uses the preprocessor to generate
+ * an invalid C construct if 'cond' evaluates to false.
+ * The following compilation error is triggered if the assertion fails:
+ * "error: size of array 'msg' is negative"
+ * The 'unused' attribute ensures that the unused typedef does not emit a
+ * compiler warning.
