Thanks for that - fixed:

I also found a minor issue involving Japanese language support. The
phrases were Yahoo Japan-specific, but I assume they also apply to
people who use regular Yahoo chat with a Japanese locale. There was a
preproc condition involving this. Based on the comment next to the
condition, I think I came to a sane conclusion:

I think so. Aside from the language support issue, I haven't noticed any
compiler warnings, and the changes are generally trivial and obviously
correct. I've tested Yahoo with the patch and didn't notice any
problems.
