/**

* This header centralizes the declaration of our libcurl dependencies
|
|
* to make it easy to discover the oldest versions we support, and to
|
|
* inform decisions about removing support for older libcurl in the
|
|
* future.
|
|
*
|
|
* The oldest supported version of curl is documented in the "INSTALL"
|
|
* document.
|
|
*
|
|
* The source of truth for what versions have which symbols is
|
|
* https://github.com/curl/curl/blob/master/docs/libcurl/symbols-in-versions;
|
|
* the release dates are taken from curl.git (at
|
|
* https://github.com/curl/curl/).
|
|
*
|
|
* For each X symbol we need from curl we define our own
|
|
* GIT_CURL_HAVE_X. If multiple similar symbols with the same prefix
|
|
* were defined in the same version we pick one and check for that name.
|
|
*
|
|
* We may also define a missing CURL_* symbol to its known value, if
|
|
* doing so is sufficient to add support for it to older versions that
|
|
* don't have it.
|
|
*
|
|
* Keep any symbols in date order of when their support was
|
|
* introduced, oldest first, in the official version of cURL library.
