[Bug: 21.5-b28] setting input-method to japanese-canna brings only No Canna API support!?

[Stephen J. Turnbull]

Please remove duplicate arguments (--with-xim is mentioned twice,
there may be others) and reconfigure and rebuild your XEmacs.  Let us
know how it works out.  Thanks!

No, it is not compiled with canna.  That would be reported in
Installation; see below.

Here's --with-canna, but ...

Here you have --with-canna=no.  I believe that the argument parsing
loop is such that the last one wins.

Note that Canna is not listed here:

It should contain the line

  Compiling in support for Canna on Mule.
