It has already been removed in the CVS and it is trivial to get the 
formatted logging message by overriding WriterAppender::subAppend(const 
LogString& msg, apr_pool_t* p) which gets the message after formatting 
but before encoding or writing to the destination.

I've committed the changes to the CVS to get early feedback on 
compilation problems with applications using log4cxx.  log4cxx doesn't 
build on all the supported platforms or pass its self tests just at the 
moment but I expect at a subset of the appenders to be usable within a 
few days.

You will have to clarify your request.  Block could mean several 
different things in this context.
