Check implicit type conversions in make_rng_state

[luhuhis]

Do we have to worry about the implicit type conversion from long int to unsigned int in this function?
lrand48 returns long ints, the aux_* variables are initialized as int, but later they are put into uint4 structs. Is this intended or just a small oversight?
