* 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.

typedef char msg[(cond) ? 1 : -1] __unused
