log4cxx no longer depends on cppunit and the expat dependency should  
be indirectly through apr-util, so you could likely drop building and  
--within those.

I haven't seen this before, but it is possible that a slight  
difference between the forward declaration of apr_thread_t in src/main/ 
include/log4cxx/helpers/thread.h and the definition in ../apr/include/ 
apr_thread_proc.h might be resulting in having two slightly different  
versions ofapr_thread_t* in scope.  Or possibly the calling convention  
(LOG4CXX_THREAD_FUNC in log4cxx/thread.h) is slightly different than  
in the APR header.

Don't have that MinGW environment handy, so can't give you a quick  
workaround.
