Don't quite follow you, but the only "tagging" now is the import declaration
(CURL_EXTERN). Apps now needs to use the same calling convention as libcurl
since symbols are decorated/mangled differently. E.g. in MSVC or Watcom using
fastcall, "curl_easy_perform" becomes "@curl_easy_perform_at_4". Hence not
specifying the cconv directly in <curl/*.h> would cause a link-fail.
(The rule for var-arg functions is an exception; they are silently
converted to cdecl decoration).
