sigset_t is a signal set, which I believe is a bitmap internally. 
SIGALRM is just a number.  You must use the functions listed in the
sigsetops manpage to manipulate signal sets.  The correct code for your
case would be something like:

	sigset_t sig;
	sigemptyset(&sig);
	sigaddset(&sig, SIGALRM);
