+Subject: [PATCH] Fix #644. Export specializations of BasicError
+
+- Only export BasicError::setMsg which is the only implementation present in the .cpp
+- Only export BasicError specialization on __APPLE__
+
+It seems that gcc automatically adds the attribute when the visibility
+settings are set to hidden. See this link for more information:
