I'm really glad that you're helping me guess, I'm guessing too! My 
hostfile is correct and I can ping seo by short name. It is not a FQDN.

If I calling getaddrinfo with those same parameters in a test program, 
it returns success.

The game calls WS2_32::getaddrinfo in wine with nodename = "" and 
service is "0". Wine turns this into nodename = "seo" (my hostname) and 
service is "0", leaving the addrinfo structure the same.

Then wine calls

result = getaddrinfo("seo", "0", pUnixhints, res);

which results in result = -2 (EAI_NONAME)

If I write a test program like this

// includes omitted
int main (int argc, int argv) {
     struct addrinfo unixhints, *res;
     // initialization of unixhints omitted, same as in wine

     result = getaddrinfo("seo", "0", &unixhits, &res);
     printf("%d", result);
     return result;
}

results in result = 0 (success).

How can wine get a different result from my test program?
