Rubbish. :-) RC4's internal state is 256 bytes. In theory, its cycle-of-repetition is 2^(8*256) bits. The current library PRNGs are quite a bit less than that. > 2) Implementing rand(3) with RC4 can be possible only if seed (i.e. > state) can be stored in single word (due to rand_r()) restrictions. This is true. Sort of. But in this case, things get less easy. Hmm. I need to look at this some more. Thanks!
