You forgot to link in the C++ libraries, as instructed in 'readme.1st'. 
If you didn't read that file, please do so.  You can link the libraries
either by adding '-lgcc' (or -lstdcx or -liostr) to the end of your
command line, or by substituting 'gxx' for 'gcc'.

P.S.:  void main() is illegal C/C++.  main() must always return an
integer.  If you add '-Wall' to your command line, it will catch lots of
pesky little errors that you probably wouldn't find otherwise.
