Hmmm, where does HAS_POSIX_MEMALIGN come from? Furthermore, GNU convention would
be HAVE_POSIX_MEMALIGN...

   // posix_memalign is not exposed in some Android versions, so we fall back to
   // memalign. See http://code.google.com/p/android/issues/detail?id=35391.
   ptr = memalign(alignment, size);
