+    # 1. We aren't cross compiling
+    #     pjsip thinks we are, this is fixed somewhere between
+    #     revision 4305 and 4621. This should be removed when
+    #     this formula is updated to 2.2.
+    # 2, 3. Clang compatibility
+    #     This is fixed in revision 4588 and should be removed
+    #     when this formula is updated to 2.2.
