I guess "likely" refers to my subtle error, rather than a 64 bit libcurl
problem.

Anyway, I see a potential problem:

I'm calling curl_formadd like so:

> curl_formadd(&formpost,
> &lastptr,
> CURLFORM_COPYNAME, element_name.data(),
> CURLFORM_NAMELENGTH, element_name.size(),
> CURLFORM_COPYCONTENTS, element_contents.data(),
> CURLFORM_CONTENTSLENGTH, element_contents.size(),
> CURLFORM_END);

and the Qt size() methods return an int. However, it's
just occurred to me that curl_formadd is a varargs fn,
so I guess I need explicit casts to long to make sure this
works reliably across different architectures.

I'm not yet sure that that is the problem but it's clearly
worth trying.
