changes to curl library have broken compatibility with xmlrpc_inetd_server

[Douglas Goodall]

I have been using xinetd to run xmlrpc_inet_server (see examples/cpp) and it has been working perfectly, until early this morning when it stopped working. I believe this is because the curl library has changed.

Here is my syslog traffic:
