CURLE_FTP_COULDNT_STOR_FILE is now known as CURLE_UPLOAD_FAILED. This is

because I just made SCP uploads return this value if the file size of
the upload file isn't given with CURLOPT_INFILESIZE*. Docs updated to
reflect this news, and a define for the old name was added to the public
header file.
