We don't support gcc prior to 3.4 any more, and I'm currently not sure  
that 3.4 still works (4.0 or better is recommended).

If you use the supplied Makefile, you can just follow the compilation  
instructions:
http://www.gecode.org/gecode-doc-latest/PageComp.html

For compiling individual examples, just run
make examples/knight

Oh, I didn't know that.  I guess it should be possible to install gcc  
from sources.  Unfortunately, we cannot support earlier versions of  
gcc, as we heavily rely on several C++ features that older versions  
just don't provide (or at least not correctly).
