+- update to 2.8.5:
+  * speedup unaligned copies by always using word shifts (in
+    combination with builtin byte swap 64 when available) when
+    bit-endianness and machine byte-order are opposite
+  * add ``HAVE_BUILTIN_BSWAP64`` to header
+  * avoid misaligned pointers when casting to ``(uint64_t *)``
+  * add tests
