Thanks Dan - that worked.

However when I generated the libcurl source, I saw that the --get
command caused the post field data to be added to the URL. This implies
that I cannot use the curl_easy_setopt CURLOPT_POSTFIELDS option to set
the web service query string, but must append it to the url (as per the
working example above). This will work, but it makes the libcurl code
messier. I tried setting the CURLOPT_HTTPGET parameter to 1, but this
failed as before. Is there any way I can use the CURLOPT_POSTFIELDS
option, or I must I create the URI myself and use it as paramter for the
CURLOPT_URL option ?
