+Subject: [PATCH] GCC: Can't use alignas() together with __attribute__()
+
+It's because GCC has problems when mixing the alignas() together with
+__attribute__() (that is used to export the symbols). The best
+solution is to use ALIGNAS() macro from //base/compiler_specific.h
+together with alignof() to have the equal functionality that compiles on
+GCC as well as on clang.
