* regint.h (PLATFORM_UNALIGNED_WORD_ACCESS): The value of

  UNALIGNED_WORD_ACCESS should be used to determine whether
  unaligned word access is allowed or not. After this commit,
  ./configure CPPFLAGS="-DUNALIGNED_WORD_ACCESS=0" disables
  unaligned word access even on platforms that support the feature.
