Just out of curiosity, can you elaborate how/why the test is usefull on other
archs? Besides some (IMHO) realy bad hacks I can't imagine why this if would
The only thing that springs to my mind is checking for arbitrary ints passed
insted of enum values, which I would test via a double cast in this case:
if ((unsigned int)arg > (unsigned int)BAZ) /* arg not in enum foo */
But basically I would consider such calls illegal.
