Thanks for that hint!

I played a bit with that option, but it does not solve my particular
problem. When I do an FTP transfer with CURLOPT_NOBODY, the write
callback is called with the 'faked' HTTP-like "Content-Length: %" (which
is ok), but an attempt to get this size after the transfer with a
curl_easy_getinfo() with CURLINFO_CONTENT_LENGTH_DOWNLOAD returns a size
of 0.

I guess this is a bug and will most likely be solved with the changes
mentioned by Daniel Stenberg in his "Kicking out the HTTP-like responses
from FTP?"-thread.

Until then, would you think it is a save hotfix to call
Curl_pgrsSetDownloadSize() from the implementation of the
ftp_state_size_resp() routine in ftp.c?

Thanks,
   Christian
