Christian Beier fe10226cc9 Fix building with Visual Studio 2008
This older Microsoft compiler does not support mixing declarations and
code and misses some error defines. This commit enables building with
VS2008 by moving up some variable declarations and defining error
codes to their WinSock counterparts in case they're not defined.
