ports: Use memalign or _aligned_malloc, when available. Fallback to malloc
...
Using "_WIN32" to decide,
if the MSVC extensions _aligned_malloc / _aligned_free are available
is a bug that breaks other Compiler on Windows. (OpenWatcom as Example)

Use memcpy instead of memcmp for unaligned memory comparisons.
...
Use memcpy because it is better supported for compilers that support unaligned
access than memcmp.
