Subject: * 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.
