True, but since curl can be linked to a completely different libcurl at run
time, removing the options at compile time won't be reliable. Some could be
easily removed at run time instead by checking the libcurl --features, but
others can only be checked by checking the output of the corresponding
curl_easy_setopt call. What might be more useful is having curl display a
warning if a curl_easy_setopt call returns CURLE_FAILED_INIT (or any other
error code, actually).
