Nice idea, but I'm not sure it would work (i'm not very familiar with __thread,
etc.): are we sure that with that kind of declaration the strtof & co functions
themselves automatically use that new "improved" errno instead of the global
one? Besides that, from a correctness point of view, I don't think we want to
fail in case of underflow, other implementations behave differently from v3...
