From 4fa9fd843e19d041a6b142722e1f2c717a45f625 Mon Sep 17 00:00:00 2001
From: Haru <haru@dotalux.com>
Date: Mon, 12 Jan 2015 18:29:24 +0100
Subject: Blocked compilation of plugins that use unavailable functions

- Rather than failing at runtime, plugins that try to access
  non-interfaced, unavailable functions or variables, will now show an
  error at compile-time.
