It is because Synapse is compatible with Delphi3, and this Delphi 
version not have any Int64.

In my plans is add some IFDEFs for this and other critical places 
(SNMP, etc.) and add support for int64 if it is possible.

Connection timeout is hardcoded in network stack.

Have you look how it is implemented in Indy? It is really terrible 
construct by another thread, and I see it as workaround, not as good 
implementation. I rather live with default hardcoded timeout, rather 
then Indy's way. But maybe... ;-)
