curl 8.16 changed CURLPROXY_* definitions from enum{int} to long.
C++ has more rules than C, preventing some implicit conversions
involving enums. Debian patch changed to instead use an explicit
conversion. [-jengelh]

http-curl.cpp: In function ‘int rtHttpUpdateAutomaticProxyDisable(PRTHTTPINTERNAL)’:
http-curl.cpp:702:27: error: invalid conversion from ‘long int’ to ‘curl_proxytype’ [-fpermissive]
  702 |     pThis->enmProxyType = CURLPROXY_HTTP;
