That is a bug in version 0.10.0 Local 2 and higher was not implemented
correctly. See this difference to see the cut-and-paste error:

<http://svn.apache.org/viewvc/logging/log4cxx/trunk/src/main/cpp/syslogappender.cpp?r1=613005&r2=654960&pathrev=654960&diff_format=l>

It has already been fixed in the trunk version of the repository. See
this revision:
