F23 wraps it like this: /* Clang feature detection: http://clang.llvm.org/docs/LanguageExtensions.html */ #ifndef __has_feature #define __has_feature(x) 0 #endif #if (!defined(__clang__) && ((__GNUC__ > 4) || (__GNUC__ == 4 && __GNUC_MINO R__ >= 3))) || \ (defined(__clang__) && __has_feature(__alloc_size__)) #define G_GNUC_ALLOC_SIZE(x) __attribute__((__alloc_size__(x))) #define G_GNUC_ALLOC_SIZE2(x,y) __attribute__((__alloc_size__(x,y))) #else #define G_GNUC_ALLOC_SIZE(x) #define G_GNUC_ALLOC_SIZE2(x,y) #endif Please open a bug on the distro to backport this fix.
