[Message part 3 (text/plain, inline)]

Now DFA does not support collating element and equivalent class for
multibyte locales at all, as POSIX does not give us any APIs to refer
to locale data to support them.

Even if DFA has supported them, they will be very slow and other codes
will be prevented from optimizing.

This patch removes codes to support them.

Thanks, I installed that patch.  If you configure with --enable-gcc-warnings 
(which I recommend), the patch causes GCC to complain about an unused variable 
wc2.  I fixed that by installing the attached further patch, which adds a minor 
optimization.
