Test fails on 32-bit kernels with:
alarm02.c:55: FAIL: alarm(4294967295) returned 2147483647 as unexpected
because kernel alarm_setitimer() limits seconds to INT_MAX to avoid
negative timeval settings which would cause immediate expiry:
static unsigned int alarm_setitimer(unsigned int seconds)
{
struct itimerval it_new, it_old;
#if BITS_PER_LONG < 64
if (seconds > INT_MAX)
seconds = INT_MAX;
#endif
Don't test UINT_MAX.
