  New Revision: 53543

  https://svn.ruby-lang.org/cgi-bin/viewvc.cgi?view=revision&revision=53543

  Log:
    * 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.
