Actually, I think the only way to be completely safe would be to do:


int lua_number2integer_f(double d)
{
	if (d < INT_MIN)
		return INT_MIN;
	if (d > INT_MAX)
		return INT_MAX;
	return (int)d;
}

#define lua_number2integer(i, d) i=lua_number2integer_f(d)


...but that's rather a mouthful, and of course you'd need a completely
separate version for unsigned ints.
