Description of problem:
Using scim-anthy under XIM in XEmacs gives an error when Space is inputted
when scim-anthy is in "ascii" (_A) mode.

How reproducible:
Everytime

Steps to Reproduce:
1. Execute:
# yum install scim-anthy xemacs
$ scim -d
$ export XMODIFIERS=@im=scim
$ xemacs -vanilla
2. Switch scim-anthy to "_A" (ascii) mode with mouse say
3. Input Space in XEmacs window.

Actual results:
3. "  not defined" appears in message window ("minibuffer").

Expected results:
4. Space to appear in buffer.

Additional info:
I haven't seen this in any other XIM apps, so this is likely
a XEmacs XIM bug.  Workaround is to turn off xim for xemacs.
Apparently scim-anthy is the only IM which uses xim for ascii input
