Hello,

I'm trying the compile the C++ version of PowerLoom version 3.2.52.  Runnin=
g
make from .../native/cpp/stella gives copious errors similar to:
hierarchy.cc:97: error: cast from =91stella::Object*=92 to =91stella::boole=
an=92
loses precision.  This error refers to what seems to be a recurring theme
throughout PowerLoom's C++ codebase.  Just wondering why the boolean cast i=
s
required.  Also, wondering why its not compiling for me, when clearly this
idiom must have worked with gcc at some point.  I'm running 64bit Ubuntu
Linux 9.10 with g++ version 4.4.1.  Note that the code associated with this
specific error is:

    if (!((boolean)(self))) {
          stream << "!NULL!";
    }

Thanks,
Cameron Ross
