* 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. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@53543 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
