If anyone has any objections, please let me know. ------------------ From: Matthias Kaehlcke commit bfb38988c51e440fd7062ddf3157f7d8b1dd5d70 upstream. clang generates plenty of these warnings in different parts of the code, to an extent that the warnings are little more than noise. Disable the 'address-of-packed-member' warning.
