Well considering I just saw a post recently saying `find` + `mkdir` is Turing Complete, I sure as hell hope C99 is as well.
The limit of "Must run infinitely" will basically wreck any computer that will fit in this universe, won't it?
EDIT: Thanks for correction to rule 110

They also updated their proof (not saying whether it's valid or not, just updated):
On a given implementation of C, a pointer has some specific size (let's call it S). This means that we can address 2^S bytes of memory. Each byte has CHAR_BIT bits, so can be in 2^CHAR_BIT states, meaning we have 2^(S + CHAR_BIT) possible states memory can be in. Since there's a finite number of states, it's not a Turing machine.

`socket()` has entered the conversation.
