/* A simple synchronous XML-RPC client program written in C, as an example of
an Xmlrpc-c client. This invokes the sample.add procedure that the
Xmlrpc-c example xmlrpc_sample_add_server.c server provides. I.e. it adds
two numbers together, the hard way.
This sends the RPC to the server running on the local system ("localhost"),
HTTP Port 8080.
