//{$DEFINE WINSOCK1}
{Note about define WINSOCK1:
If you activate this compiler directive, then socket interface level 1.1 is
used instead default level 2.2. Level 2.2 is not available on old W95, however
you can install update.
}
//{$DEFINE FORCEOLDAPI}
{Note about define FORCEOLDAPI:
If you activate this compiler directive, then is allways used old socket API
