I see SF ate my attachment again. As a reminder, warn1.patch is available at http://www.limegreensocks.com/mingw-w64/Home.html.

Ok, I have made the change for __attribute__((gcc_struct)). It appears that clang also doesn't support 'selectany' either as a __declspec or an attribute. Given how many places define this, perhaps this change should go in _mingw.h? I'm thinking: #if defined(__arm__) || defined(_ARM_) #define DECLSPEC_SELECTANY #endif ------------------------------------------------------------------------------ What NetFlow Analyzer can do for you?
