I can compile Dolfin 0.5.6 without problem using gcc 3.3.4. However, I had a
problem when compiling /src/kernel/mesh/Tetrahedron.cpp with gcc 3.4.3. The
error is 

./dolfin/Face.h:97: error: `dolfin::PArray<dolfin::Edge*> dolfin::Face::fe' is
private

It compiles without problem if I add

friend class Tetrahedron;

to /src/kernel/mesh/dolfin/Face.h. Below is the full error message.
