Older curl releases do not define CURLE_HTTP_RETURNED_ERROR, they use CURLE_HTTP_NOT_FOUND instead. Newer curl releases keep the CURLE_HTTP_NOT_FOUND definition but using a -DCURL_NO_OLDIES preprocessor flag the old name will not be present in the 'curl.h' header. This patch makes our code written for newer releases of the curl library but allow compiling against an older curl (older than 0x070a03) by defining the missing CURLE_HTTP_RETURNED_ERROR as a synonym for CURLE_HTTP_NOT_FOUND.
