+    NACL ifdefs.
+
+    There are two main classes of functions:
+
+    - Functions that are called but can have no effect:
+    For these we simply give an empty implementation
+
+    - Functions that are referenced in the source code, but
+    is not/must not be called at run-time:
+    These we either leave undefined or implement with a
+    qFatal.
+
+    This is a work in progress.
