My go-to place for cURL version information is:

https://github.com/curl/curl/blob/master/docs/libcurl/symbols-in-versions

and it says CURLOPT_USE_SSL has been available since 7.17.0.  If
7.16.4 was the last version in the 7.16.x series, then these two
sources are consistent.

[2] says that the feature was available under a different name in
the past and up to version 7.16.4, meaning with 7.16.4, USE_SSL was
not usable. You'd need to do "<= 7.16.4" on the title, but it is
simpler to follow the symbols-in-versions table and say "< 7.17.0",
I would think.

The patch text looks OK.
