It appears at the bottom of the file when viewed through the Web CVS  
interface:  
http://cvs.apache.org/viewcvs.cgi/logging-log4cxx/src/ 
consoleappender.cpp?rev=1.11&view=markup.  Something in the file had be  
use std::wcout for you to get your previous message.

Likely you defined _GLIBCPP_USE_WCHAR_T as "" instead of 1.  However  
that won't do the trick since it is a that environment variable should  
be set when the C RTL is built.

I found this bug in the GCC Bugzilla that seems on-topic:  
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=6702.  Can you try using  
GCC 3.4 or later?

If not, fix per the previous message or comment out whatever was  
causing the compilation problem with std::wcout and std::wcerr (which  
would make ConsoleAppender ineffective) and see if that is the only  
compilation problem encountered.
