shimbun requires mule feature on XEmacs?

[Yoichi NAKAYAMA <yoichi@xxxxxxxxx>]

Hi, while I test Wanderlust pre-release version on XEmacs without
mule, I found that shimbun.el cannot be loaded on it. I got attached
backtrace. Is it the known issue or I missed some information about
shimbun does require mule feature?
