socks server sample - conn structure bug

[ac]

The "uv_connect_t connect_req;" member of "conn" structure in defs.h should not be inside "union t" because used in same time as "t.addr4" in connect request. So t.addr4 contents overwrites the t.connect_req.

I've moved connect_req on level up, and now socks server works under Windows too. ... uv_connect_t connect_req; union { uv_getaddrinfo_t addrinfo_req; uv_req_t req; struct sockaddr_in6 addr6; struct sockaddr_in addr4; struct sockaddr addr; char buf[2048]; /* Scratch space. Used to read data into. */ } t; ...

[txdv]

can you do a pull request of that change?
