ERROR_LOG is defined as:
   if(true) { \
   std::cerr << __FILE__ << ":" << __LINE__ << " ASSSERTION FAILED: " << 
a << std::endl; \
   abort(); \
   } else (void)0


Anyway, I've created a patchfile (/home/hson/generator_private.hpp.diff 
on buildfarm) which at least makes generator.cpp compile, but I can't 
assure for functionality.
Basically I've added "return tpoint(0,0)" for those functions returning 
tpoint and "return NULL" for those returning twidget.
