Hm... can we introduce at least a little entropy somewhere?
Mh? A user is supposed to seed via srand().
Then why initialize y at all?
To have a sane fallback. Maybe i should have written
"A user is supposed to seed via srand() if he wan't some
entropy."
This is inconsequent. Either we assume that the user will seed srand(), then y should not be initialized at all, so it goes to the BSS segment and does not waste space in the binary image. Or we want to deal with cases where the user doesn call srand(), and then we should provide a bit better than such a static initialization.
Again, i wanted to stick with the regular rand() srand() semantics.
http://pubs.opengroup.org/onlinepubs/009695399/functions/rand.html "If rand() is called before any calls to srand() are made, the same sequence shall be generated as when srand() is first called with a seed value of 1."
But i'm fine with removing the initialization.
