GCCs before 3.2.x have different C++ ABIs, so if you call/use any external 
C++ library (say, libstdc++ :-), it won't work.
The ABI is being standardized from 3.2.0 onwards, barring any bugfixes.

If your code runs as a stand-alone executable (ie. not inside a library), 
you might try to link it statically against any C++ library, thus not using 
the system ones.
g++  -static should do this.
