Ok. I did some reading.

It's perfectly fine to call it more than once. It is, in fact, NOT ok to
call it from DllMain, so the auto-run bit would be extra bad.

So I'm going to vote for leaving this how Jobin had it. If the calling
app needs other sockets, they can call WSAStartup and be fine. If the
calling app just wants to talk to Drizzle, they can just use the library
and also be fine.
