back/x11 XIM fix [was: Re: Gworkspace with non-fragile abi, etc?]

Hi,
Thanks for the feedback. I'll just address this one question:

Yes, XIM should work with cairo (or any of the graphics backends, as long as 
the window server backend is x11). However, it looks like I broke XIM support 
over a year ago. :-( I just committed a fix for now: 

        * Source/x11/XIMInputServer.m: Add the setlocale(LC_CTYPE, "") call
        back that I removed last year (r35152).

        I tested the fcitx input method, and without the setlocale call,
        XOpenIM would fail. I'm not sure what the best plan is in the long
        term, I wanted to avoid calling setlocale from the core frameworks
        but in this case xlib seems to require it.

To test gnustep with fcitx, I ran:

export XMODIFIERS=@im=fcitx

in my shell before launching Ink, and then was able to press ctrl+space to 
enter Chinese characters.

Could you try doing an svn update on core/back and see if the fix works for you?

Cheers,
Eric
