Description

I get this bug at revision 598875 - I just can't build more new revision because of LOGCXX-218.

I maked a very simple Win32 console application:

===
#include "stdafx.h"

#include <log4cxx/logger.h>

int _tmain(int argc, _TCHAR* argv[])
{
return 0;
}
===

But even this simple application produce a lot of warning:

Maybe I get these warnings because of incorrect log4cxx distribution - I didn't find target "dist" and just make svn export for main\include\log4cxx.

What I'm doing wrong?
