CVC head not working under Windows?

[bruce_np]

I tried the ant build of the latest CVS head.
The build worked till dthe test part where I got an exception.
Then I used the DLL in my test appl, and found that an exception is thrown
in the folowing code fragment:
CharsetDecoder::CharsetDecoder(const char* frompage) {
#if LOG4CXX_LOGCHAR_IS_WCHAR
 const char* topage = "WCHAR_T";
#endif
#if LOG4CXX_LOGCHAR_IS_UTF8
 const char* topage = "UTF-8";
#endif
 apr_status_t stat = apr_xlate_open((apr_xlate_t**) &convset,
    topage,
    frompage,
    (apr_pool_t*) pool.getAPRPool());
 if (stat != APR_SUCCESS) {
   throw IllegalArgumentException(topage); // <== throws exception
 }
}
So what does that mean?
Am I doing something wrong, is something missing, ....???
And another question: Is there also a way to build a release version of 
the DLL ?

Best regards
