Build Log.

Turns out that OpenSSL declares heaps of the codebase as static, while LibreSSL (at least, v2.7.4, as I'm using) does not in many cases.

Wrote a quick patch to address this.

Created attachment 553574 [details, diff]
patch to change static declarations to dynamic, assuring compatibility with LibreSSL 2.7.4

Note that we're using LibreSSL 2.7.4 - I'm not certain if this is much of what's making that particular unmask a challenge, but I do enjoy finding out.
