   I did add a hack to 1.9dev4. If you compile with -DWORKER_HACK it
   will work just fine. But just after I committed the change to the
   CVS I realised there is a much more elegant solution - LoadFile.

   Simply add:

   LoadFile /lib/libgcc_s.so.1

   to the configuration file. If this works for you I will remove the
   WORKER_HACK stuff from the code. Let me know.
