Why on earth do they define all these errno values when there's nothing in
winsock that uses them?

It seems we have to (for VS2010 builds) #undef all errno defines we use and
#define them ourselves unconditionally to their WSA* equivalents. Don't you
guys agree?

The current setup_once.h seems to allow the compiler's errno.h values to have
precedence over our own definitions, do we need to keep that or can we just
#undef + #define all errnos independently of VS version?
