When running "config.guess" it fails to recognize the operating system. See output in the mail body.

Dear Sir or Madam,

First: Happy New Year!

Please see between the dash lines the output of "config.guess". I 
therefore used the newest "config.guess" (and "config.sub") that I had 
downloaded from 
"http://savannah.gnu.org/cgi-bin/viewcvs/*checkout*/config/config/config.guess"; 
and 
"http://savannah.gnu.org/cgi-bin/viewcvs/*checkout*/config/config/config.sub";, 
respectively.

If you need additional information, please feel free to ask me.

Could you please inform me when an update "congig.guess" (and 
"config.sub") is ready? Or how can I fix the problem by myself?
