Try tweaking it and compiling with -m32.  your compiler probably
compiles 64-bit code by default.  I sometimes find commenting the
self.dict["CXXCOMSTR"] (for C++, similar for C and assembly) helpful in 
trying to find out what exact flags the build system is passing to the 
compiler or assembler.

I do not think it currently has a standard C++ library.  It may be
possible to port an existing one.  On Wombat however, you
can of course run C++ applications.
