Tested with gcc 4.5.1 and following were not supported: option: -Ofast macros: _Static_assert __ORDER_LITTLE_ENDIAN__ __ORDER_BIG_ENDIAN__ __BYTE_ORDER__ __atomic_fetch_add __ATOMIC_ACQUIRE __atomic_load_n __ATOMIC_RELAXED __atomic_store_n __ATOMIC_RELEASE It is not easy to fix all in PMD, disabling PMD for older compilers.
