Now we depend on having at least cURL 7.19.5 because
CURL_SEEKFUNC_{FAIL,OK} are not available before that version.
cf. https://github.com/curl/curl/blob/master/docs/libcurl/symbols-in-versions#L127
Which is fine, as 7.19.5 is from May 2009 that is old enough. We
just need to update the place where you got the 7.19.4 above from.
Thanks.
