On platforms where unaligned access is not an issue, gcc produces for memcpy() an optimal binary code equivalent to simple assignment of 32-bit value. Only MSVC produces slow code, but Windows works only on platforms where unaligned access is not an issue. So we can use simple assignment when _MSC_VER is defined and memcpy() in other cases (it is what I was proposed in issue19183 for PY_UHASH_CPY).
