Probably because of this change, building Emacs got to fail (on
at least Cygwin platform).  Before the change (96a8e8) it's ok.
An output of make is below.  Where I added (setq debug-on-error t)
to `skkdic-convert-postfix' in "lisp/international/ja-dic-cnv.el".

Note that Emacs tries to load the file named "...".  I couldn't
find how `lookup-nested-alist' calls `load-with-code-conversion',
sorry.

Thanks.
